The flickering isn't supposed to happen. Btw, can you figure out which screen lines flicker? Do all of them flicker, or just some? And if you disable relative line-numbers (i.e. use absolute line-numbers), do the lines still flicker? all of them? > E.g., Dmitrii, do you have some > display-related software/driver that has some "optimization" features > turned on? If so, can you turn them off and try again? Did you try looking for such features on your system?
