After some more testing, I found that the cursor jumping around still happens
without that commit, so that's not actually it. I did some more bisecting and
got it down to this:

841214ddb4 made the mouse completely stop working in Age of Empires II, even in
the game menu. a0f039a604 made it work again, but during the actual game, the
mouse cursor sometimes jumps around randomly. For example, when making a
selection by dragging, the selection rectangle corner sometimes jumps to a
corner of the screen. It's not easy to describe.

The 3c023a5db5 commit I mentioned before affects general graphics performance
and makes the mouse problem noticeably worse. But reverting this alone doesn't
fix the problem.
