Does is also crash if you uninstall nvidia binary drivers?
Did you *only* open the compositor settings ("kcmshell5 kwincompositing") or did you choose "More Actions/Window manager settings" from the titlebar rightclick menu? In case this is reproducible, is it also reproducible with *only* the compositor kcm (run "kcmshell5 kwincompositing")?
Created attachment 93053 [details] Step 1
Sorry - I wanted to add screenshots :) btw to be 100% precise - it is 100% reproducible on 2 independent PC's - step 1 - choose More Actions/Window manager settings (Rendering engine is OpenGL 3.1) - step 2 - change Rendering engine to OpenGL 2.0 ( do not apply change) - step 3 - go back to previous value (3.1) - step 4 - click Cancel button - error message will appear. I am using Nvidia driver. Will do that test on another PC with intel graphics card later.
This has probably nothing to do with the driver or even the compositing kcm. Please close the dialog and (from konsole or krunner) run kcmshell5 kwincompositing this will open only the compositing config dialog. Try to cause the crash there and report back.
When invoking the settings dialog by this command: kcmshell5 kwincompositing issue is not appearing.
This is most likely related to bug #346748 then. And apparently the approach to avoid it failed =(
Unfortunately the backtrace is missing debug symbols. This makes it impossible to proper investigate. If you are still able to reproduce please install debug symbols and attach a new backtrace. Sorry that we forgot to ask you about this really important step in a timely manner.
