REAPER for Linux bugs

[Jack Winter]

Please post bugs that you think are related to running REAPER on Linux in this thread.

[Glennbo]

The wet/dry sliders and highlights for them seem to be offset to the right in ReaComp.

Edit: This is on Xubuntu XFCE with an nVidia GPU.

[Andrew479]

No such issue on my arm install:

Maybe themeing? Mine looks more or less ok too

It does appear to be theme related.

When I choose the stock theme, the fader handles are now in line, but overlaying large empty white vertical rectangles.



Choosing the 4.0 theme makes mine look like your screen shot. My normal theme is LCS Short Dark, which uses mostly UI bits from Imperial.

[kytdkut]

Not a bug, but I dont think this ruler font is configurable. It does not follow any font setting anywhere (theme tweak tool, libSwell.colortheme)

The small number is fine, also it's not theme related.



Anyone having this issue?

(obv a small thing, but it triggers my brain :P)

The theming seems to have gone a little weird in 5.94, buttons look flat and you can't see which is selected, like this with the band tabs:

Hi,

Strange thing in Extensions/Auto Color/Icon/Layout. I have tracks in different colors and MCP Layouts. When I type in right MCP Layout the same string ends up in Icon column and the one in MCP dissapears, you need to doubleclick to see it again.

Using Commala theme, tried default same thing

On instrument tracks I have white faders
On bus and effect tracks I have blue faders

Deleteing in Icon column doesn't work. I have to remove the whole thing.

It works but I thought I should mention it

Attached screendump, couldn't get it to show both columns.

Reaper 5.941

[doppelganger]

alt+click on effects in mixer doesn't work, can delete effect only from right click menu,
Ubuntu Studio x64, Reaper5.95pre5

same goes to scripts, gfx.mouse_cap should give 17, but it doesn't react to alt+click at all.

alt+leftdrag on fx button moves the whole Reaper window.


Edit:
p.s. aha, for some reason it uses ctrl+alt instead of alt

That would have to do with your windows manager. By default it uses alt-click to move windows. On kde I replaced the default for moving windows with logo-click, which makes all alt-click work in reaper. There might be other shortcuts eaten by the WM/DE, so it might need some customization.. How to do so, would depend on what you are using.

looks like the fader section is being widened in Linux for some reason.
Look at the Threshold fader and you can see it has some of the same issue.
Looking at the other examples it is clear that the fader background is being stretched, but in a passable way.
This appears to be due the way the Linux version renders this part of the theme.
If it's not possible to fix in Reaper, then it may be possible to make a work-around with a different background.
These vertical faders would also need to be changed.
I'll see what I can do.
It may take a while, since I'll need to set up a Linux/Reaper install to make and test it.

The stock default theme is kind of messed up too. It's missing the graphic slot on all faders, plus other UI elements, but the older 4.0 theme looks totally lined up with nothing missing or mis-aligned.

Makes me think there may be newer Walter functionality that wasn't yet in use in the 4.0 theme. I could be way off base too, but either way it's not keeping me from using it, and I totally prefer using LCS Short Dark as my one big screen theme. :-)

Reaper Version: v5.941 - August 4 2018

It happened to me already three times that REAPER crashes out of the blue when clicking into the time ruler while a song is playing. I didn't observe this with other versions and I can't reproduce it.

I also use Commala and I love the colors and layouts. Gonna try yours, it looks awesome.

This is not a bug, but. Any chances to get this pin in Linux Reaper?

(In the meantime, you might be able to make it happen with your window manager. In KWin at least you can set up special window rules for this kind of thing. Not the same, of course, but might help.)

Here are some issues related to VST preset dropdown that I noticed with TAL Noize Mak3r:
1. Can't use up/down arrows or mouse up/down to change to previous/next preset
2. Can't click the dropdown to easily set focus, need to use tab and left/right arrow keys
3. Pressing the down arrow while dropdown is focused opens the dropdown instead of going to next preset
4. Opening the dropdown always starts from the top of the list even when the current preset is at the bottom (requiring to scroll down to the current preset)

I've noticed that there is something not right with the midi editor and inline editing. If I have a project with quite a few Reaverbs or LSP Impulse Reverb using impulses for stuff like reverb then the playback is massively affected by opening a midi item or inline editing. I get stutters and slowed down playback when midi editing is enabled.

There is a particular some I am working on and it's nearly impossible to edit midi, even without the song playing when I open the editor my mouse goes slow and audio goes really slow. Now, this song is quite heavy with plugins and tracks but the performance meter only shows about 49% cpu use. I'm running jack at 1024 so certainly not pushing it.

The strange thing is that when you have the editor open and it is stuttering as soon as you close it the playback is fine, instantly. I would say it's like the midi editor is very cpu intensive but Reaper isn't using huge amounts of CPU when this happens.

The only thing I can pin it down to is using impulses. I noticed that in the LSP plugin if I change the FFT Frame to a high number across all instances it helps. Same thing with Reaverb.

Anticipative processing is turned off on tracks with open MIDI editors by default. Enable the corresponding option in Preferences > Audio > Buffering.

[Jack Winter]

And check out the zl/ll checkboxes

[cfillion]

Speaking of Linux bugs: gfx.getfont from the API always returns an empty font name string. https://forum.cockos.com/showthread.php?p=2022793



(EDIT: FontConfig for font family recognition & flexibility instead of the hard-coded font filename scanning SWELL currently does would be nice too, I guess)

Thanks, that seems to do the trick.

That helps when using reaverb but shouldn't be acting like that with other plugins.

[Jack Winter]

Might help when rec arming tracks.

Edit: When I think about it, I guess it's tangential to the discussion, still a good trick to lower rt cpu in some situations.

[cfillion]

Changing the selected FX by manipulating the track state chunk ("SHOW n") instead of using TrackFX_SetOpen is broken (SWS does that, it should probably be updated to use the newer function but this still looks like a bug in REAPER on Linux).

The selected item in the chain's list is updated but the new FX is only briefly showed before it goes back to the previous FX's UI. TrackFX_GetChainVisible and GetTrackStateChunk still gives the old FX's index.

Would be nice if someone gave some example code of how to do it using FontConfig...

awesome, thanks!

Edit: while I have you, have some code to enumerate the available font faces installed on the system (for the font browser)?

Edit again:

I've started on the intergration, http://1014.org/shiz/shup/fontconfig.patch

Things to address:

1) The fonts in REAPER and libSwell.colortheme etc being mapped differently (can we set preferred fallback fonts?)
2) App-local fonts (we include liberation sans and a modified version of Bravura) -- can we shove these into our instance of fontconfig?

Sorry for asking you here -- if there's a programmers guide somewhere for fontconfig I'm happy to look at it, the documentation I could find was never a "how to use this", just a reference of each function...

Alt+Click to delete FX in the MCP isn't doing anything here. Shift+ to bypass and Ctrl+Shift+ to offline are fine.

Ubuntu Studio, 5.941.

I don't think this is a bug. The Alt key is a system modifier in many Linux desktop environments for moving and resizing windows and globally blocked. In that case change the modifier key to another one like the hyper key or windows key.

Fair enough. I wonder if it would be worth having a preference somewhere for "treat the __ button just like Alt" to get around that.

I, um, also can't find anywhere to change that particular shortcut. It's not an action, not seeing it in Mouse Modifiers either.

Edit: Problem solved. I just used US's "Window Manager Tweak" app and changed the "grab windows" key to Win.

Here's how fc-list does it: https://cgit.freedesktop.org/fontcon...fc-list.c#n172.

FcPattern *pattern = FcPatternCreate();
FcObjectSet *properties = FcObjectSetBuild(FC_FAMILY, FC_WEIGHT, FC_SLANT, FC_INDEX, FC_FILE, nullptr);
FcFontSet *fonts = FcFontList(s_fontconfig, pattern, properties);

for(int i = 0; i < fonts->nfont; ++i) {
  FcPattern *font = fonts->fonts[i];
  FcPatternPrint(font);
}

FcFontSetDestroy(fonts);
FcObjectSetDestroy(properties);
FcPatternDestroy(pattern);

Thank you! Seems to work well except on files containing multiple fontfaces (like .ttc fonts). FC_INDEX from the hit pattern should be given to FT_New_Face.

I don't understand what you mean by "being mapped differently", but fallbacks are usually configured through system-wide or user XML files. They can be loaded from code too with FcConfigParseAndLoad or FcConfigParseAndLoadFromMemory.

FcConfigAppFontAddFile(s_fontconfig,
  (const FcChar8 *)"/opt/REAPER/Plugins/Reavura.otf");

(An application font is not given priority over a system font if the later is deemed better.)

I've pushed some WDL public changes which works to my satisfaction. You will need to change a line in your libSwell.colortheme in order to keep the same appearance as the old mapper, from "default_font_face LiberationSans-Regular" to "default_font_face Liberation Sans". Other than that it all works, woot.

Setting wnd_vis=1 under [mastermixer] in reaper.ini causes a segfault for me.

Running the application under gdb or valgrind gives no indication of a segfault happening, so my guess is it's a Heisenbug.

Here's the relevant crash info I was able to get from the kernel logs:

If it helps any, I'm on i3wm, a tiling window manager.

[shosty]

Jackwinter, I've just tried the libswell theme you uploaded, it looks great but the value popup when you move a fader is just a yellow/white square. Is there a setting somewhere that controls that? Just using the default reaper theme if that makes any difference.

[Jack Winter]

That doesn't happen here, at least if I understand you right. Tried with the default theme too, where I get dark menus but some dialogs look a bit funky being bright instead of dark.

I must admit that I'm not a great themer and I didn't put much effort into this. It was quickly done to demonstrate the new capability and then put to the side.. I'm still using it with a dark theme that I downloaded and have modified a bit.

Probably better if some real themers added this for their themes, but as it only works on linux I guess that might be wishful thinking.

FWIW, on my system the popup is dark grey with white text..

I know that Justin did some changes to it not so long ago, but I'm not sure exactly what. I suppose maybe some things might still get overridden by the theme in use.

Edit: Mystery solved. The libSwell.colortheme I uploaded to the stash is indeed wonky, have updated it, so download and try again...

It also has a different font, to go with changes in 5.95pre7. Also some dialogs get dark, and others are determined by the theme...

If it helps any, I'm on i3wm, a tiling window manager.

Can you grab WDL sources and build a debug build of libSwell:

git clone https://github.com/justinfrankel/WDL.git
cd WDL/WDL/swell
make -s DEBUG=1
ln -sf `pwd`/libSwell.so /path/to/reaper/libSwell.so

then we can at least see the libSwell symbols in the crash trace...

Alternatively: can you email your reaper.ini to support at cockos dot com and I'll try duplicating with i3wm but of course if it's a heisenbug...

None of the Toolbars: Switch to toolbar 1 actions are doing anything here. (5.941)

Another one - reaper.ExecProcess doesn't appear to do anything.
