Description Joe Krahn 2002-11-14 15:46:31 UTC
From Bugzilla Helper:
User-Agent: Mozilla/4.79 [en] (X11; U; Linux 2.4.18-17.8.0 i686)

Description of problem:
I get serious artifacts when rendering with ATI DRI using
lines with smooth+depth, or bitmaps with depth test enabled.

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

How reproducible:

Steps to Reproduce:
1. Compile and run attache test programs.

Actual Results:  Very broken rendering, as if the depth buffer is getting filled
with random data.

Expected Results:  Normal rendering.

Additional info:

The distributed Mesa demo /usr/bin/aapoly also renders incorrectly.

I posted the bitmapbug example to the DRI group a few months

I haven't been using ATI DRI for a long time because
it always caused system lockups. Finally, the RH 8.0 XFree86
is stable, but the rendering is still broken. So, I'm back to
compiling my own, or disabling DRI.

Please attach your X server log, config file, and /var/log/messages
from after a problem event has occured.

X server log

This log is actually from a different system with different hardware
and a different ATI card, but the artifacts are the same.

Just tried this in RH 9. Everything works OK. Wow. This is actually
the first time in all RedHat releases that DRI ATI has worked for
my application that does mostly smoothed lines and bitmap text.

Comment 6 Mike A. Harris 2003-04-15 09:10:04 UTC
Great to hear.  Closing as CURRENTRELEASE of RHL 9
