--- Comment #32 from Tom M tmwine@pertho.net --- Debian Bullseye (oldstable) has Mesa 20.3.5 and Void Linux (which is pretty bleeding edge) has Mesa 23.3.1.
So.. if Mesa is at fault, then a memory leak was introduced between those versions is my guess.
I'm not even sure how I'd go about downgrading Mesa as a test. I guess I could see if that have a bug tracker but even then, how would we determine it's Mesa and not WINE?
