Bug ID: 447956
Summary: Wayland: inverted DBUS-notifications appear in app
title bar

Screenshot of a corrupted title bar.
SUMMARY
When using Wayland with Nvidia 470.86-46, sometimes inverted parts of DBUS
desktop-notifications appear in title-bars of unrelated applications.
I'm not sure if it has anything to do with the bug, but the DBUS-notifications
have a 30 second timeout. They are being raised by jouno, a systemd-Journal
viewer which features Freedesktop/DBUS Notifications forwarding (
https://github.com/digitaltrails/jouno ).
STEPS TO REPRODUCE
1. Raise a lot of notifications.
2. Sometimes a notification corrupts an unrelated application's title bar, but
I cannot predict when.
OBSERVED RESULT
Part of an notification will appear as inverted text in the title bar of an
unrelated application.
EXPECTED RESULT
The notification should not be able to corrupt the title bar of an unrelated
application. Presumably this is also security issue given Wayland is supposed
to isolate each app's windows.
