Title:
  too many mesa_shader_cache_db files open

Status in mesa package in Ubuntu:
  Fix Committed
Status in mesa source package in Oracular:
  In Progress

Bug description:
  [ 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.
