<pre wrap="">Could you do some benchmarking? You can disable XShm support by

It would be useful if some people using Nvidia, intel or EXA based
drivers could compare the results of the test app attached to this
mail with and without XShm. A test on ATI fglrx is not useful at this
point because it doesn't use an EXA-like architecture yet and they
don't accelerate XRender in hardware yet.
Thanks,
Roderick

The test was build with "i686-pc-mingw32-gcc -m32 -o blt_test test.c
-lgdi32 -lcomctl32", I couldn't get winegcc to compile it (path issues
- wine is not installed, I'm running it from an out of tree build).<br>

Why does the test run two times on wine and only one time on xp?<br>
