Hello,
it seems that this patch introduced a nasty bug (at least for me). With "DesktopDoubleBuffered" = "N" wine get's a SIGSEGV, tries to start the debugger, next SIGSEGV looping forever. The SIGSEGV happens in DefaultScreenOfDisplay (X function) called from X11DRV_GDI_Initialize and that one is called by process_attach (x11drv_main.c) . Setting "DesktopDoubleBuffered" = "Y" 'fixes' the bug.
Any idea?
bye michael
P.S.: i'll open a bug report but at the moment i'm too tired.

Hmmmm, I just tried it here (with my own tree, not with the version merged by Alexandre in CVS but it should be similar) and I have no crash even when setting the option to 'N'. I tried both in Desktop and non-Desktop mode and both work fine.
Could you run Wine with gdb and in Synchronous mode and attach to the bug report you will raise ( :-) ) or by private mailing me all the information you could obtain at the moment of the crash (ie where it crashes, the value of the display variable, ...).

Yes, i couldn't reproduce it myself on a second machine and i started to think that i'm crazy. After the first shock I did a diff of the configs of the two machines and found the needed info to make the bug reproducible: "DesktopDoubleBuffered" = "N" AND "ScreenDepth" = "8" need to be set.

Oh, now that the bug is reprocducible i silently hope(d) you could gather them yourself ;). If you still need my help feel free to shout.
