Which video driver? SDL 1, SDL 2, or (unlikely) Allegro?

SDL1, I think.

Playing in 1.10.1 now; problem still persists. Also, a savegame with the issue (which i forgot to attach originally)
test, Jan 1st, 2010.zip

On Windows 10 Home 10.0.18363 Build 18363, moving the cursor a lot can cause the cursor to disappear (and/or be cut off) for a bit. Unfortunately, I was unable to capture that in a screenshot, but it happens in practice. It is better reproduced with an empty map.

@James103 : upcoming nightly (that of 20210223) will have that fixed (see #8726).

@CheeseSprinkles : we did a lot of improvements on rendering in general, but I have never seen this issue in all the testing I did. Now there is a chance this is fixed in our latest nightly (https://www.openttd.org/downloads/openttd-nightlies/latest.html ). Would you mind giving that a spin to see if the problem is resolved?

Tnx!

Given the video drivers have essentially been rewritten in the last few months, I will consider this resolved, as any similar will be a completely separate
