Additionally, things like glxgears & vkcube slow to a crawl when picom is active, though I havent tested various configurations to see if they fix all my problems yet!

Update: doesn't happen if vsync = false. Same with the massive performance hit mentioned in the footnote

[noctuid]

Welp, I guess I'll set vsync false for now. I'm also seeing this, though my system was often completely freezing not just slowing down.
