There is something making my KDE crash. Every time I try to re-enable OpenGL and change any configuration on compositor (see image below) or any desktop effect or animation, it resets (after closing system settings or rebooting. I have even tried to snapper my machine to a time point before the problem appears but it still remains).

This is my production machine, and using Virtual desktops is paramount for me. Unfortunately, because of this problem every time I reboot the machine my virtual desktops disappear
Not to mention windows effects that are a deal breaker like darkening inactive windows...

So, it seems that all features/effects that are implied by the compositor OpenGL are not functioning or reset to a non functioning state after every reboot (because of the compositor bug).

I appreciate all help
