When trying to work on any document, new or opened, the brush, zoom or any action except the warp around feature is unresponsive. Any brush stroke I try to make doesn't show up or any movement around the canvas. The display catches up if I hit the warp around key (W), but otherwise I can't see anything I'm doing. I've tried restarting the program, my computer, and reinstalling the software, but there's no change. There was a recent Windows 10 update and that's the only thing I can think of that's breaking Krita.
You'll have to update your intel display driver or disable opengl: 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
