Bug description:
[ Impact ]
When running IntelliJ IDEA in an X session with Mutter and an nVidia
graphics card and proprietary drivers some dialogs have a semi-
transparent background making it hard to read any text in those.
The bug was originally reported here:
https://youtrack.jetbrains.com/issue/JBR-6983
Then an issue was filed against Mutter and successfully resolved:
https://gitlab.gnome.org/GNOME/mutter/-/issues/3600
The resolution has been confirmed by several people building Mutter from
source as is supported by comments here:

[ Test Plan ]
1. Set up a machine an NVIDIA GPU running Ubuntu 24.04 LTS and the
proprietary NVIDIA drivers
2. Log-in to a GNOME Xorg session
3. Install IntelliJ IDEA Community Edition from the App Center
4. Open IntelliJ IDEA Community Edition
5. Open or create a new Project
6. Hit Ctrl+N to bring up 'Search Classes' box
7. Type '/' in the search box to populate the results
8. Verify that the background of the floating box is solid (non-translucent)
9. Press backspace to delete the '/' character
10. Repeat steps 7~9 for 10 times, ensuring that the floating box is never
translucent
[ Where problems could occur ]
mutter is the component of GNOME driving the screen and inputs, and
thus is a critical component of Ubuntu Desktop.
Problems could manifest as applications rendering with the wrong colors, such
as an inverted effect or other artifacts.
At worst the user may be suddenly logged-out in case GNOME Shell crashes
because of a bug introduced by this patch.
