AV after turning the screen off and on

[den13x]

I'm using Windows 11 23H2 (set HighDPI = 150% i.e. Settings -> System -> Display -> Scale = 150%), Delphi 12.1 (v29.0.51961.7529), CnWizards v1.3.1.1181 (only "Source Highlight Enhancements" and "Debugger Enhancements" are enabled).
Problem: I’m working in Delphi, I leave the computer, after some time the monitor turns off (energy saving), after I return to the computer and the monitor turns on, Delphi becomes smaller when I try to work in Delphi or expand Delphi to full screen (Maximize), then the following error appears:

This problem also occurred in Delphi 11, 11.1, 11.2, 11.3, 12.0. CnWizard is always the latest version.
Restarting Delphi helps solve the problem. Or turn off, then turn on "Source Highlight Enhancements"

Thanks for your help. Seems our painting object associated with Delphi EditControl corrupted, we'll try to check how it happens.

Thanks!
The same error occurs if I change Windows Scale from 150% to 100%, then:
