Can't reproduce on X11, but perhaps it's because my computer is slow so the glitch has disappeared before I can see it.

Maybe because your window is small. With a bigger size I can see the grid is redrawed with every change and creates the visual glitch.
I would say this is a minor issue. At least with dedicated GPU in X11 is barely  noticeable.

Cannot reproduce on Wayland.

On my system the glitch is a bit different after recent updates and I can't reproduce consistently anymore.
I'm attaching another screen recording.
