Blurry apps in overview

[amadeusp]

The contents of application windows are blurry and fuzzy when displayed in GNOME 46.3.1's overview.

@konstantintutsch the issue is caused by commit 1c0e89c and is explained in the description of that commit:

fix: display windows correctly in overview

Previously, when opening the overview, the corner rounding was removed
from windows themselves and applied to window previews.

This prevented the windows from being slightly blurry, but after a
Mutter update, the code that was handling this broke, and window preview
sizes were calculated incorrectly.

This commit removes this behavior. It means that windows in overview
will be a bit pixelated, but it isn't very noticeable, and certainly
better than the windows being half transparent. Maybe the blurriness
issue will be easier to fix in the future, after I refactor the
codebase.

This happens because of a bug in upstream GNOME (quite easy to reproduce, steps described in the issue I opened): https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/7903

I've not yet understood how to hack beyond it, but if I find how I will tell you!

I'm locking this since it's an upstream issue and it's up to Gnome to fix this

@aunetx please ping me somewhere else if you find a way to work around this
