As I had originally suspected, this has nothing to actually do with BGRA4
format. It was just an odd place in the command stream.

The following patch should fix it:
https://patchwork.freedesktop.org/patch/78448/

Please test. I think this has been broken since mesa 10.2 or so =/

FTR, in the trace, things go wrong between call 722316 and 722358. In the
middle, a SRGB8_ALPHA8 texture is created, and receives an upload from GL_BGRA
+ 4_4_4_4_REV data. According to qapitrace, that data is not properly reflected
in the texture.

Running this with llvmpipe, the first glTexSubImage2D clears the data (all 0's)
while the second glTexSubImage2D uploads the font. Since the font texture
contains garbage, so does the remaining rendering. Need to figure out why the
texture upload fails with the data in question.

http://workupload.com/file/rmdaFRu0 in 6.2.4 also has that corruption.
I tried with both wine 1.7.55 and 1.9.6-staging.
It starts with small missing pieces and gets worse if you maximize the game
window.

Argh! You're right :( Just retested with latest mesa and the trace you
originally supplied didn't work. But I *swear* it worked for me at commit
d68226087c. Maybe it was through luck? Or perhaps something in st/mesa changed
and it's taking a different path now...

Diablo 3 seems to be hitting the exact same issue, BTW.

I tracked down these issues to *something* to do with BGRA4 transfers.
Commenting out the two BGRA4 formats in nv50_format.c "fixes" it for me.
However no RGBA4-related tests appear to fail, teximage-colors is all happy,
etc. So there's something more subtle may be going on.

Since this isn't show-stopping for the game, I think I'll keep looking into
this without pushing out any shotgun fixes.

Should also double-check on a tesla to see if perhaps fermi+ have shed support
for that format. But my guess is something in the blitter.

Actually I ended up just pushing something that removes it on Fermi and newer.
I tried to get the blob to use that format, but couldn't. This leads me to
believe that for whatever reason it is no longer supported. Or... something. I
double-checked that it still works on tesla though.

nvc0: remove BGRA4 format support

Something is wrong with the support somewhere. I couldn't get the blob
driver to use it either, although it happily used RGB5_A1.
teximage-colors works, but WoW seems to fail in the menus for drawing
text.

Another note: I did play the game some with these UI issues present and I did
not notice any other kind of rendering problems whatsoever. It appears to
affect only the UI and text and absolutely nothing else.
