how did you get anything higher than Mesa 25.0.0-devel? i have the Kisak PPA but it wont install anything past Mesa 25.0.0-devel.
This one kisak-mesa fresh : kisak? That version shouldn’t even be available there, it never even was.
Make sure you have added it correctly, it seems you are getting your mesa from somewhere else still.
When you mention “mouse acceleration”, are you referring to just mouse pointer tracking on screen?
I’m on Ubuntu 25.04 and the update rate of the cursor on screen is just broken. if there is no graphics on screen, It might only update once or twice per second. I’m finding just having GLXGears running in the corner is the only way to use the system :-/
Different issue there is that GLXGears only runs at 30 fps, when it should be at 60, as I have 2 60hz monitors connected.
Kernels used:
6.14.0 (various, tracking ubuntu PPAs)
6.15.1 - 6.15.4, (tracking ubuntu mainline PPAs)
Various Mesa versions tracking Ubuntu updates & Kisak (even using libs for ubuntu 24.10 in an attempt to fix)
Anyone else see this issue?
glxgears will run at whatever the screen’s refresh rate is set to, double check the refresh rate your monitors are actually set to, it could also be doing some kinda weird half refresh rate vsync?
What’s the output of running xrandr in the terminal?
Yes, sounds like the same issue.
I had crashes and worse performance with Fedora, so I switched my gaming PC to Arch Linux. This was at a time when I was switching most of my other Fedora systems to OpenSUSE Tumbleweed anyway. (I want to build another system around Intel’s Core i9 285 at some point in the near future and put Fedora on that, though). Also, at this point, I’m waiting on a new PSU to arrive; I kept tripping overcurrent protection on my old one.
Refresh rates are set properly. xrandr is a bit bulky, but does show the 60hz set. gdctl shows this also:
:~$ gdctl show

Dang. Okay.
kisak just dropped properly for 25.04 too, and still no dice there.
It feels like a power management issue somewhere.
Tested quickly on nobara live cd, kernel 6.14.6, no issue (KDE). Curious.
That inspired me to try Kubuntu 25.04 LiveUSB. GLXGears is 60fps & mouse seems “fine” (it’s seems not perfect but it doesn’t stutter).
Suspicion is raised about Ubuntu/Gnome/Wayland configs.
