Mouse stuttering with Linux 6.1 due to PSR on GNOME #11

Closed stuarthayhurst closed 1 year ago

stuarthayhurst commented 1 year ago

After updating to linux 6.1-rc3, the mouse began stuttering on the desktop, except when the screen was forced to refresh. For some reason, panel self-refresh (PSR) is causing this, but not either earlier kernels. Regardless of the root cause, using amdgpu.dcdebugmask=0x10 disabled PSR in the amdgpu driver, and the mouse works again properly (source code reference).

Documenting in case anyone else has the same issue, feel free to close this :)

Can probably be closed if #12 is merged

Might be worth creating an issue on the kernel bugzilla if it has not already been reported, otherwise this may end up in the 6.1 release.

I plan to as soon as I have the time spare, I'll get to it later today hopefully

Seems like this has been fixed by linux 6.1-rc5, as I can't reproduce this anymore.
