Hi Denis,

Thanks for your message.
Well, the GPU sometimes hangs a few seconds or a few minutes after I launch
supertuxkart. It happens faster if some other application that needs the GPU is
running. For example, with SMPlayer (mpv). While the computer is frozen, I can
still hear SMPlayer playing. There is no overheating (I fully cleaned my laptop
last summer, even changed the thermal paste). CPU tops at 65ºC under load, and
35-43ºC when idle.

I tried a few things : disabling IOMMU and other stuff in the kernel
parameters, recompiling a custom kernel for Arch, creating a new user
profile... Nothing helped. I tried in latest Debian testing: same result. I'm
starting to suspect VA-API or any GL/DRM related stuff, so I'll keep on testing
but I'm a bit lost. By the way, I always use KDE Plasma.
Unfortunately, I have reinstalled the whole computer and now use Gentoo. But
the issue also occurred when I tried before trying in Arch. So I'll post the
result of the command of the apitrace when it happens in Gentoo (the kernel and
Mesa versions are different).
Cheers,
Chris
