Firefox's UI sometimes glitches in and out

[DUOLabs333]

Describe the issue
Sometimes, when the mouse is moved over a Firefox (v114) window (so when Firefox refreshes its UI), sometimes icons disappear. However, this usually only lasts for a second, as if you move your mouse over, it usually fixes it. I should note that only icons glitch --- text stays the same (though any svgs on a webpage may also glitch). Through bisection, I determined that it is a mesa issue (downgrading far enough fixes the problem); in particular, it is the commit specified here: #4983.

This was fixed in a later version of mesa/Firefox/QEMU.
