No matter what tool I use, I can't see what I'm doing. I try to sketch, but I can't see anything. Once I click outside of the canvas, I can see what I did. I haven't had any success trying to fix this. I can't sketch without being able to see my art.
This is an bug with openGL on laptops that use intel graphics cards. We're currently testing an alternative way of handling the openGL here:
It would be super useful if you could give that a spin(and fill out the survey :) ). If you don't want to try it, you can also try to go to settings->configure Krita->display and toggle openGL.
(Though, it be really really really super useful if you could at the very least check, we really want to fix this bug once and for all :) )
