Morning, Gents.

I run the TurtleWoW World of Warcraft client, which is the original WoW client
from Blizzard, but with substantial modifications made by the TWoW devs.

I updated Wine to 10.0.

Prior to this, I could alt-tab without problems back to desktop (XFCE on
Debian) quite a few times, maybe ten or so, but in the end environmental
textures would all turn black and I would need to quit and restart the client.

As of 10.0, I can alt-tab *once* without problem.  The second time I alt-tab,
when I come back to the WoW client, its screen is simply black.
