--- Comment #1 from Wylda <wylda at volny.cz> ---
Confirming. Please always describe most reliable and easiest to reproduce
issue. In this case, it is games's login menu (missing upper-left & upper-right
corners). Or even better - initial "Loading..." screen should display 3
cogwheel. When this problem is present, they are missing and you can only see
the "Loading...".



Introduced by commit wine-1.7.0-51-g37d1e8b:

commit 37d1e8b79cfc2c4ca7b947589574179470a06c42

    wined3d: Try to avoid redundant constant updates.

    This gives a minor performance improvement. For example, in 3DMark03
    Game Test 1 this gives about a 4% improvement, in the Counter Strike:
    Source stress test it's about 1%. (NVIDIA GF9600M, Intel T9550, 1024x768).


Revert makes this problem go away.

This is reproducible only if "UseGLSL"="disabled". Please note the console
line:

err:winediag:wined3d_dll_init The GLSL shader backend has been disabled. You
get to keep all the pieces if it breaks.
