With Proton 6.3-5 and 5.13-6, games launched through either do not set the _NET_WM_BYPASS_COMPOSITOR flag to 1. This means that the X11 compositor in use does not know to unredirect itself, leading to worse performance and higher VRAM usage. I cannot set my compositor to manually disable without killing it, which is undesirable. This bug affects every Proton game I have downloaded (around 10), but no native titles

Hello @katawful, there's no value in fragmenting the discussion at #4469 over multiple issue reports. Closing as a duplocate.
