I have no idea if or when it was a regression. My report just states that it is happening for me now (with these video drivers, hardware, etc).
Let me know if you'd like me to diagnose it further. It's totally reproducible.
Testing an older version of wine to see if it is a regression, and if so, running the regression test would be very helpful in diagnosing this bug.
