Title:
Windows get wrong z-index and flickering decoration halo
Status in gnome-shell package in Ubuntu:
Incomplete
Bug description:
Frequently, windows such as the new text editor, or the nautilus file
browser, or modal dialogs seem to have an in valid z-index, i.e. I
cannot click the title bar, and the window is virtually behind
everything. The window also has a flickering halo full of garbage
from other screen areas which looks like missallocated texture memory?
It is possible to bring the window into the foreground, bu e.g. TABing
through the applications but it cannot be used because other windows
that are 'behind' it capture the mouse events through this window.
This can happen with many Windows at the same time, typically after
sleep-wake. The Windows can be rescued into normal state by using
keyboard shortcuts to maximize-minimize, after which everything is
fine. The z-index is correct, mouse events are captured and the
decorations look perfect.
This started happening with Ubuntu 22.10 and is still present in
23.04, so I assume that it is a bug in Gnome 43? This happens
regularly after sleep wake which, in my case, often comes with a zoom
switch between 100% (external monitor on dock) and 200% (internal
HiDPI laptop screen). I am running Ubuntu on xorg, not Wayland,
because screen-sharing individual windows with Zoom does not work on
Wayland. I am observing this most frequently with Snap apps such as
Nautilus and the new text editor, but also Evolution dialogs have come
up with this. May be a timing issue that manifests more frequently
with the slower snap apps?
I understand that this bug-report is unsatisfying in how to reproduce this,
and what exactly the outcome is, but it is pretty random in nature and I can
only report the visual/ GUI outcome. I am happy to provide additional input as
requested.
