RE: partial freeze when playing 3D games

I discarded LXDE as a problem as the same happens with KDE

Asunto: partial freeze when playing 3D games

 

Hi all,

When running 3D games (video players or 2D games work fine), at a random moment the image freezes. If I Alt-Tab out of the game window, as shown in the linked video below, the Alt-Tab dialog works and it actually switches to the other applications but they can't be seen, only their window borders. I can even do Alt+F2, type xterm, the application opens and I can type exit and xterm is closed. The only thing I can do is go back to text mode with Ctrl+Alt+F1, log in and kill the game process, then go back to Alt-F7 and everything works fine with the remaining open applications.

I checked Xorg.0.log and other files in /var/log and dmesg, but there is nothing there related to the freeze. How can I further debug this?

System: Debian 11 + LXDE, all updates applied

Linux 5.10.0-8-amd64 SMP

VGA compatible controller: Intel Corporation TigerLake GT2 [Iris Xe Graphics] (rev 01)
