Hello there.
I bought Krita on the 15th of June and launched it but the main Window is some sort of Transparent. I reeinstalled the program several times, restarted my pc several times and downloaded all recent drivers for my graficscard and the program but it still is transparent. I also installed Krita on my laptop and there is everything right. I hope someone can help me soon.
Greetings Kiseno.

Change the Canvas Graphics Acceleration in Configure Krita -> Display from OpenGL to ANGLE.
Cheers

Thanks that worked
