[ Impact ]

Applications might exceed the limit of open files, 1024 by default, because mesa opens the mesa_shader_cache_db files too many times.
This is a regression in mesa 24.2 where the shader-cache got re-architected.

[ Test Plan ]

1. Install gstreamer1.0-plugins-bad
2. Install gnome-control-center=1:47.1.1-0ubuntu1 from oracular-proposed
3. Run `gnome-control-center mouse`
4. Verify that Settings launched correctly
5. Close Settings
6. Verify that Settings did not crash
7. Run `gnome-control-center system`
8. Navigate to the Mouse & Touchpad panel
9. Move the cursor outside of the window
10. Verify that Settings did not crash
11. Close Settings
12. Verify that Settings did not crash

[ Where problems could occur ]

Mesa is a critical component for the Desktop or any systems with a GPU.

The mesa shader-cache may not work correctly.
Performance may be degraded.
