Description ux.010101 2020-12-02 02:02:55 UTC 
Description of problem:
SELinux is preventing gdb from 'open' accesses on the chr_file /dev/dri/renderD128.

*****  Plugin catchall (100. confidence) suggests   **************************

If you believe that gdb should be allowed open access on the renderD128 chr_file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# ausearch -c 'gdb' --raw | audit2allow -M my-gdb
# semodule -X 300 -i my-gdb.pp

Similar problem has been detected:

Often, when switching windows, the GUI locks up, my sessions is closed and I'm presented with the login greeter.
After logging in, I get a bunch of these sealerts.
My guess is, it's trying to report on the original failure but can't because of the selinux violation.

Best I can tell, this is related to abrt trying to handle a crashed application.
