Got a new laptop w/144Hz and 60Hz display frequencies available, installed Hirsute.

Same problem, this time when trying to switch to 60Hz :

As a side note, on Wayland sessions, it seems it tries to behave like it did switch to 60Hz, with glxgears vsyncing at around 70Hz. Strange...

I suppose I should go upstream for this bug, since it doesn't seem it will be addressed any time soon here. I didn't mod my EDID yet, but the workaround likely still works. I will come back if it doesn't.
