You're not telling us anything useful... And I doubt you're on Linux. I'm guessing you're on Windows, that your problem is an issue with the display driver on your system (https://docs.krita.org/KritaFAQ#Krita_starts_with_a_black_or_blank_canvas_and_nothing_changes_when_you_try_to_draw.2Fshows_a_black_or_blank_screen_on_my_Windows_system_with_an_Intel_GPU), and that the issue will go away if you test this version of Krita, which has a workaround: https://krita.org/en/item/krita-3-3-0-first-release-candidate/ . *** This bug has been marked as a duplicate of bug 360601 ***
