Description Jure Repinc 2011-06-23 05:02:36 UTC 
After I updated my mesa and restarted X the KDE Plasma desktop and apps were displayed wrongly. Some parts were just black and what was visible was all reddish. I bisected the commits and the first one causing problems is:

1a339b6c71ebab6e1a64f05b2e133022d3bbcd15
st/mesa: prefer native texture formats when possible.

If I disabled KDE Kwin desktop effects the display was OK.

I'm using KDE software version 4.6.4, Linux kernel 3.0.0-rc1, libbdrm and xf86-video-ati are from git.

try to undo the damage

Can you try this patch?  It disables choosing the Gallium formats that have no counterpart in Mesa.
Comment 7 Brian Paul 2011-06-23 07:18:13 UTC 
BTW, I've added a new piglit test that catches the regression from the commit in question: texture-packed-formats

I've found that this patch also fixes a crash during Steam login. :)

FWIW, the same commit causes the game ETQW to segfault on start, and log these
errors:

EE eg_state_inlines.h:388 r600_translate_colorswap - unsupported colorswap
format 67
[...]
Mesa 7.11-devel implementation error: _mesa_texstore_null() is called
[...]
FATAL ERROR: Image '_quadratic' was generated with internal format 0x8051 but
GL returned 0x1

The patch fixes the segfault, but doesn't make the game render correctly.

fa5478c5fe88e9c07d30203984b712925de84d2e with the patch takes care of the problems with ETQW.
