My answer on bugzilla:
I see it so, gdb wants to read something in the mesa_shader_cache and AVC denies and blocks lightdm
Please could you also follow on Cursor freezing by login screen (lightdm) upgraded to Kernel 5.16.7
that i not have to say everything twice. I do have colleagues there who help me to debug.gdb (GNU gdb (GDB) Fedora 11.2-1.fc35) tryes to access:

Feb 11 08:56:13 fedy setroubleshoot[1866]: SELinux is preventing gdb from open access on the file /var/lib/lightdm/.cache/mesa_shader_cache/index.@oprizal proposed to follow the redhat links to check the selinux part. everything was fine.
Then i deleted the files/folders under /lib/lightdm/.cache and restarted.For the moment it is ok.
What more info’s could I give ? Can i check somehow what gdb wants in the /lib/lightdm/.cache folder ?
