Description Rich Wareham 2003-04-08 09:54:12 UTC
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.2.1) Gecko/20030225

Description of problem:
Texture, depth buffer and shading corruption when using OpenGL, DRI + r128
drivers. Fresh upgrade from RH 8.0 to RH 9. No previous problems with RH 8.0.

Screenshots showing corruption available at

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
Run some OpenGL program using the r128 drivers that come with RH 9.

Additional info:

Not tried reproducing with upstream release of X. Quick google for previous (non
RH-related) problems with r128 driver turns up nothing. Similarly the XF86 CVS
ChangeLog mention any fix for a similar problem.

XF86Config is standard one generated by install. Unmodified since then.

Comment 1 Mike A. Harris 2003-04-08 10:39:34 UTC
This looks like a Mesa bug of some kind, probably in the R128 Mesa DRI
driver.  Please report this bug directly to the DRI project via the
XFree86.org bugzilla:  http://bugs.xfree86.org

I will track the DRI project's progress on the issue and if a patch becomes
available, I'll add it to future XFree86 packages.

Please update this bug report once you've filed it upstream and provide
the URL so I can track it.

Reported to upstream bugzilla, bug #120:


Comment 3 Mike A. Harris 2003-04-08 11:41:37 UTC
Thanks for the quick update.

Comment 4 Mike A. Harris 2003-04-12 15:55:02 UTC
Thanks.  Changing status to UPSTREAM.  I'll scan the upstream bug report
from time to time to see if it has been fixed, and see if it can be
backported if possible.  If you find any new information, feel free to add
it here and there also.

Updating upstream bug URL for reference:


The upstream URL indicates this is believed to be fixed in newer
release of DRI/Mesa code, which has since been integrated into
XFree86 (and thus X.Org X11 also, which is our current X11

Closing bug as "RAWHIDE".  If the problem persists in rawhide
xorg-x11-, you can file a bug report to the current
upstream bugzilla, which is http://bugs.freedesktop.org in the
"xorg" component.  The DRI project has merged into X.Org,
so X.Org bugzilla is the official DRI bugzilla now.  If you
do continue to reproduce the problem, and file a bug report in
X.Org bugzilla, if you also paste the new bug URL here, and
reopen, we will track the issue upstream in the new location.

Thanks in advance for testing the new X release.
