Bug Report Unable to capture program window [Question/Help]

[A2000]

So I was finally trying to update to OBS Studio, but, where OBS did this just fine and not problems, OBS Studio is failing, and when I try to capture AIMP3 window (Music player)
OBS just captures the "Size" of it, but displays whatever is in front/back of it.

OBS Studio example of this capture not working:

OBS Working correctly and doing what you expect. You even have options to Crop/Trim and capture an specific region, thing that I didn't see on OBS Studio.

Any ideas on how to fix this? Thanks a lot.

PS: Let me add that even on Monitor Capture, the AIMP3 Window is invisible.

PS: Adding to the problem.

If I use AIMP2 the window is captured correctly. Don't know what that means, but something on how AIMP3 works makes it so OBS Studio doesn't see it and think it's transparent.

I'm having the same issue; whenever I try to capture a game using a window capture, OBS just shows what was behind the window when it launched.

Here's my log file; it seems the program is unable to find a certain device:

For reference, the first window capture ("Ori") is of Ori and the Blind Forest Definitive Edition while the second ("Refunct") is of Refunct, a game I have previously recorded and streamed using OBS. The LiveSplit capture present in both scenes works correctly.

I noticed I needed to manually install an update and am currently on version 21.1.2, but I'm still having the issue. Nothing appears to have changed in the log: https://hastebin.com/imebehuyit
