Hello everyone

I use Krita 4.2.5 on windows 10, recently my Krita is slightly transparent, the software works properly but it is impossible for me to draw.

I think the problem occurred during a theme change.

I tried uninstalling, deleting the cache files (Roaming and local) registry cleanup, I can not find where the backup files stored because the problem is still the same.

I attach a photo to make it more meaningful.
Thank you.

Under Configure Krita > Display try switching the preferred renderer option from OpenGL to ANGLE or vice versa and restart Krita after.
What GPU and driver version for it do you have, by the way?

Great ! Everything works again, for my processor I have a GTX 1080 in msi in 8GB with the latest drivers 417.01

Thank you so much !

I pass the thread in solved.
