Unable to bisect because of #101478 (Regression: Crash when Sculpt Mode is selected.)
I think either of 65900d88a8, 039429faeb introduced the issue.

@JosephEagar , now crash is triggered when I attempt to sculpt with dyntopo (so far I've verified in lite build only: 47d3e765679e54c09ecc4ded812e89483a1e1d9b)

But not frequently crash occurs. Will find reliable way to redo it.
And yes, your commit indeed fixes the issue :)

The garbled display is indeed fixed. I also was able to sculpt some strokes in one scene until Blender closed.
Then I gave it another try with an empty scene, a simple grid and it closed / crashed upon activating Dyntopo.
Linux / full build / latest master
