I'd like to put in my vote for returning this bug to "Major". Reasons:
1) Affected applications (which is quite a few apps for widely different
purposes) may still run, but lose substantial functionality. What good is a
video player that doesn't show videos? If this is the same bug that affects
Diablo, it makes it impossible to create a new character without memorising the
menu structure on a non-Wine solution. (Loading an existing save game is
easier.) Does that count as "an easy workaround"? I say no, because it depends
on something completely external to Wine, or a hacked version of Wine that is
known to break in other circumstances.

2) Virtual Desktop is not a workaround. From what I gather, what *is* a
workaround is getting the application to run in windowed mode, in which case
the blitting mode has to be switch by the app so that it only locks to the
window, and doesn't try to lock the whole screen. I probably don't understand
the problem correctly, but "Virtual Desktop" and "run the app in windowed mode"
are very different things, and games that exhibit this bug do not tend to have
windowed mode.

3) The only proper solutions to the bug are nearly impossible.

I wouldn't mind seeing Stefan's GL ddraw solution become an opt-in registry
option for upstream Wine.
