DirectX can't change Screen depth

[Colin Pitrat]

Hello,
I'm maintaining a game named Blip  Blop 
(http://appdb.winehq.org/appview.php?iAppId=3470), and I have some 
problems with color depth. If the X server is configured in 16 bits 
colors, it works well, but if it's in 24 or 32 bits, the app display in 
black and white, and I've got the following message :
fixme:x11drv:X11DRV_desktop_SetCurrentMode Cannot change screen BPP from 
32 to 16


Looking at the source, it seems that changing resolution is not 
implemented, and that doesn't surprise me as it doesn't seem to be a 
good idea to change X depth to please a wine app (especially if we're 
emulating a desktop). But shouldn't the 16 bits output be converted by 
wine to 24/32 bits to be displayed. Is it a problem with the way the 
game is coded (maybe it should check return code to fall back to another 
depth) ?

I've seen this in lots of games but the colours are always ok -- maybe
it is specific to that game?
