re-install
Kanshi seemed to have been the root cause of weird graphical glitches
starting sometime earlier this year. Weird flickering green and
occasional drm crashes where I lost sway for minutes at a time and it
would partially recover. Games would stutter very badly intermittently.
It is likely due to refresh rate synchronization somehow, but in my case
it's been simpler to turn it off. I'll maybe look into it again in the
future.
