Thanks a lot Damjan! How did it look in 24bit without your patch applied? 
Similar to what I reported for bug #1973 (a screenshot is attached)? Because 
that application also works perfectly with X set to 16bit, but the graphics 
are completely broken in 24bit. According to the author of the affected 
application, it's a bug in StretchDIBits, but it sounds somewhat similar to 
what you describe. Your patch doesn't affect bug #1973, BTW, but it may still 
be a similar issue...?
