Kaveri i/GPUs seem to have problems, again

Some time ago I made the post A10-7870k GPU integrated graphics not working ANYMORE, which among others led me to make a bug report on “le proper page” (it got immediately shut down with “same issue as” and “fixed + merged”; understandable, but my opinion is not what’s important here).

I wanted to report the fact that the Kaveri iGPU I am using on one of my computers is starting to malfunction again.

.

This time Desktop use seems normal (and to be honest the problems started appearing some time ago, but I was sick so I couldn’t focus on it), but there are some strange behaviors:

I mainly game and use the desktop stuff on there, I don’t use professional software, so I can only report on that.

  1. OpenGL glitches and lacks some functions. In games like Left 4 Dead and Team Fortress 2 “the lighting is flatter” and some textures are missing, replaced with pure black (like the doors, seems to be with destructible objects and objects not “backed in the map”).
  2. Vulkan doesn’t seem to be working properly. Even when running Quake Remaster under Proton it now gets just 15 FPS with everything on low.

Right now I both have little time for this and I still am somewhat sick, so I can’t clearly think about this issue on its own (I am lucky that since it’s not crucial for me I am not in a hurry),
but I’d like for this to get solved.

.

I am in absolute ignorance about Mesa Drivers development and thus its developers, so I won’t dare share opinions or comments about this.

If anything, I’d like to know why cases like Kaveri Graphics have started having problems since Mesa 25?

I just now made a page.

I was “busy” to this moment.
