When i try capture windows with xcomposite i got black screen except few apps. Capture didn't with Chrome, Steam, Terminal but if i try capture Firefox, Discord or OBS itself capture works normally.

Now i run fresh installed Ubuntu 20.04. I tried KDE enviroment too and capture works ok.

I have Nvidia 440 proprietary drivers installed and tried 435 and 390 versions too but no difference. But if i run Opensource drivers window capture work with all windows.

Log/terminal say this when i capture window which appears black capture.
"xcompcap: glXCreatePixmap failed: BadAlloc (insufficient resources for operation)"

I "fixed" this by using the default noveu drivers... very slow and laggy but it works well enough to record your terminal. I suspect nvidia is to blame for this, as per usual....

We have the same issue here as well. Brand new Dell system. Ubuntu 20.04 fresh install.
OBS and Chrome = Blank Windows Capture.
Please advise.

Same issue - Ubuntu + nvidia.

Got it to work by installing xubuntu-desktop inside ubuntu. Than, in the Ubuntu 20.04 login screen, I select xubuntu session.

Everything gets captured now.
