Application: konsole (22.08.2)

Qt Version: 5.15.6
Frameworks Version: 5.98.0
Operating System: Linux 5.19.0-35-generic x86_64
Windowing System: X11
Distribution: Ubuntu 22.10
DrKonqi: 5.25.5 [KCrashBackend]

-- Information about the crash:
Konsole had crashed an disabled trasparency.

It seems to be related to the System Settings (app) > Display and Monitor > Compositor function, as I opened it and there was a message gelated to OpenGL 2.0 being disabled.

I re-enabled it and Konsole did not recovered transparency right away (after restarting the app).

I have got a new crash message and started filling this report.

I have closed and re-opened it and now transparency seems to be working again.

It seems to be working now.

I went to that recovery scenario after testing the solutions from below links:

https://askubuntu.com/questions/1415319/konsole-has-no-appearance-preferences
(Did not worked).

https://www.reddit.com/r/ManjaroLinux/comments/dx9x40/kde_plasma_transparency_got_broken_how_can_i_fix/
(Did not worked as expected, but fixed the issue after additional steps, cited on this report).

The crash can be reproduced every time.
