I discarded LXDE as a problem as the same happens with KDE ________________________________ De: Toni Casueps Enviado: viernes, 23 de julio de 2021 8:39 Para: debian-user@lists.debian.org <debian-user@lists.debian.org> 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?
