Right, and this commit was reverting another commit --
7c510133d93dd6f15ca040733ba7b2891ed61fd1. I bet that if you check out
to right before this commit, you'll get the "general" corruption again
(it went into 3.12-rc1, the revert went into 3.12-rc2 -- I assume that
when you tested 3.11.x, the corruption was the same as in 3.12.x,
which contains both this commit and its revert).

I would like you to bisect whatever corruption you see when you tested
3.11.x -- is that the pink lines, or the flickering textures?
