Just FYI: Recently a friend of mine who plays Perfect World MMORPG under Wine
had tried to switch from using Wine 1.2.3 into using Wine 1.4-rc2 and sent me a
message complaining about major performance drop. I had spent two hours
reproducing problem on my rig (Phenom II X4 955, GeForce GTX 550 Ti 1GB VRAM,
6GB RAM, 32bit Linux, nVIDIA drivers 295.17) and then bisecting it. Looks like
between 1.2.3 and 1.4-rc2 there had been at least two performance regressions,
one of which bissected down to the commit this bug report is about. 

Stats are something like this (starting PW in window, maximized on 1680x1050
screen) for game login screen - measurements are as displayed by
WINEDEBUG="+fps":

Wine 1.2.3 - FPS ~17
Wine 1.4-rc2 - FPS ~10
Wine 1.40rc2 with commit 68b15bc5 reverted - FPS ~14

I'm still tracking down an another commit that caused FPS drop from 17 to 14. 

What I want to ask is: should I file another bug report about performance
regression in Perfect World game client caused by commit 68b15bc5 or not? I
mean, it seems that the problem with FPS drop in WoT due to commit 68b15bc5 is
- probably - just the same as I had tracked down for PW game client, so maybe
it's not convenient to track them as a separate bug report entries. 

Stefan, Dmitry, what do you think?
