I noticed something else ... while running with a lot of debug flags which made
sc slow:

After selecting battlenet and when the login screen appears, I see that the
background is properly drawn ... and then it fades out! (and not in)

I guess the last 'black' color is transparent and therefore all the rest of the
battle.net GUI is broken.

Items not being cleared, the black color instead of surfaces reminds me of a
problem with flipping buffers and clearing the screen.  

Perhaps Starcraft does its drawing of the battle.net menus in an unexpected way
that prevents it from working correctly with wine's implementation of direct
draw.

With the newest development (see previous post), I am curious to see what
happens if wine is changed so that the the back buffer and front buffer are
swapped.  Perhaps we will get the background image (without text) of the
battle.net menu.

I do not know much about this stuff, so I am currently unable to do this
myself.  Moreover, I do not know if it is even feasible.

Also, I think the battle.net menus work properly in Starcraft ran through
cedega.  Maybe we can see a diff of wine's implementation of direct draw with
that of cedega.  This is what I'm going to be doing since my ignorance will not
affect looking at differences in code as much as trying to find the problem by
just looking at wine's code.

Well, there goes comparing cedega to wine.  The direct draw code is not
released with the cvs version of cedega.

Shouldn't the importance be trivial or minor instead of normal? It doesn't look
so nice, but it doesn't affect the game functionality at all. And it's only
active on the menus, not on the game itself.

So all the graphics are being draw, but because the battle.net window
is drawn on top with a transparent background the graphics window does
not show.

The battle.net hack floating around, that does draw the graphics, does not
draw the text dialog windows.

Does this have to do with the fact that X11 does not support alpha blending,
and that what is now drawn as black is supposed to be transparent?
