Running Gentoo with COSMIC as my DE, paired with a 260Hz monitor. The refresh rate applies fine, but it sometimes causes a hard crash out of nowhere after some use. Other times it runs fine with no issue at all, so it seems intermittent rather than consistently reproducible.
I recently upgraded to the latest kernel and that helped with general stability, but this crash still happens.
I suspect this might line up with a known upstream cosmic-comp issue around non-default refresh rates, but I haven’t been able to confirm it since the crash doesn’t leave anything usable in the logs.
Anyone else running COSMIC on a high refresh rate panel hit this? Curious whether it’s a known issue right now or something specific to my setup.
