Default Play Cursor lag or stop with png's... why?

posting here since it happens in the pre... maybe in all versions... but for sure in this pre...
[mod... move if you deem it so]

see the video... I'd expect the play cursor to move smoothly along and stop.. the play cursor should be clearling showing me exactly where we are in the 'play'... not this 'stop and go' stuff.

the color items are very simple very small png files intended to provide a visual clue [cue] from afar... you will see the play cursor stops or severly pauses at the left edge of each of them... which makes using them freakin' useless.

Can't reproduce in neither pre nor official version.

Hope, what method and alpha is being used to play the cursor onscreen in your theme ?

ummm without a dbl check right now, the play cur is a custom color obviously, and I think it's 2 px [or 3] wide... don't recall the alpha setting but it is less than 100% I'm sure...

do you believe that matters???

oh shoot... seems like it's only a problem on this pc... tried it on the dual core in the other room and it works fine... this one is a single core 3.0 ghz [both are XP ]

darn, darn, darn...

ok let's look on the bright side... I'm now accepting donations for an i7 build... [hey better than giving money to some political dude, eh? ]

EDIT... a little more about this just tested:

even on the wimmpy pc, if I use the png's that come with reaper for track icons, it works OK... BUT if I use color pngs it hangs [on this pc]
this is true even if the color pngs are very small.... Now this is strange to me since even on this same pc it will play an mp4 video OK [given the good codecs]....
So I'm wondering if there is some sort of better "png codec".... I'm open to all ideas

EDIT 2... well more... making a new little set of png's that seem to work fine... 64x64 px both none and interlaced work OK.. seems to me at the moment that IF the pngs are very small they work OK even on the wimmp... that is good

I want a little set to use for 'heads up' cues [clues] that can be seen in the video window from far away... this will work

thanks for all the help and still, if you think of anything more, plz do tell.

Nothing new into this matter, but confirming what is happening.

Default theme, tossing some pictures into the track will make the playback stop for a moment, but not all of the pics have this side effect. Not directly size related it seems and occasionally when the given track has been played once, there are no stops for every pic and/or all the time. Not a prerelease issue, Reaper 4.22 does it as well, haven't checked any further back.

Single core 2.2 GHz, 32-bit, WinXP Pro SP3.

Thanak You Xpander for that ... at the least I now know I'm not alone in this and that it IS a problem that does exist.
