Hello! With my current setup, anything chromium based experienced a rather dramatic slowdown when using Picom. This behavior is most notably in Chromium browsers (Brave, Vivaldi, and Ungoogled Chromium). But I’m also seeing a slight lag in Electron based apps like Discord and VS Code.
In browsers, everything renders SLOWLY. Videos are lagging, extensions slowly open, etc.
When I kill Picom, the problem goes away.
I found this forum post
that offered a few clues.
So, turning off hardware accelerate in Brave WORKS. No video playback issues, extensions are snappy.
In picom.conf, I set fading, blur, etc., to false prior to trying hardware acceleration. These had no effect. Doesn’t seem to have an effect with hardware acceleration off.

Any ideas or suggestions for tweaks I could make to improve the response in Chromium based apps? Thanks!
