Screenshot demonstrating one of the issues

With latest GIT, some stipple patterns look pseudorandomly corrupted/rendered wrong. Also there are some update problems leaving "trails" (see the linked video), though I am not sure if that is a driver issue or a Wine issue.

Wine version is latest GIT as of today.

(And yes, I did take a look at Wine's bugtracker to see if there was anything that seemed related, but could not find anything.)

Drat, I was quite confident there would be no more damage issues.

Have you checked with --enable-debug? (Note not --enable-debug=full, though that will be useful if you have a trivial reproduction or once I have a better idea of where to such for the needle.)
