In every version of KiCad, I’ve had wandering grid problems that show up randomly. This includes all the 4.X versions of the stable release; although I have not tested the last 2 stable releases).
I have, over time, found that pressing F9 then F11 resets quite a few problems.
For grins, I repeatadly hit F9,F11,F9,F11,F9,F11… repeat. What I saw on the screen was quite interesting.
OpenGL Rendering set to Subpixel Antialiasing (High Quality).
Full screen cursor checked.
Always display cursor checked.

I’ll try to do a little more testing to have a more polished report of exactly what is happening. I hope other users will report their results as well.
Thanks.
