Default What API does WDL use to capture the screen underneath it?

What API does WDL (or is it just LICECap?) use to capture the screen underneath it?

Newer windows apps seem to not be able to read for what's underneath them for "security reasons" per this: https://github.com/Microsoft/Windows...ment-286175913

Well, LICEcap is open-source, so you could check for yourself.

BTW, I only glanced through the linked discussion, but I think it's about UWP apps, so I'm not sure if what LICEcap does even applies.

I tried looking through the code but couldn't track down where it gets this info. And when I was talking about "newer windows apps" UWP is what I meant.

Really big fan of your software by the way Tale

I think LICEcap uses BitBlt() to "cpature" (copy) screen data, see line 1203 in licecap_ui.cpp. It looks like it gets its DC via GetDesktopWindow(), which is why I suspect this might not work in UWP apps.
