Bug #: 43332 Summary: corrupted output in mesa-demo/fp-tri using r600g on evergreen Classification: Unclassified Product: Mesa Version: git Platform: x86-64 (AMD64) OS/Version: Linux (All) Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/r600 AssignedTo: dri-devel@lists.freedesktop.org ReportedBy: stefano.teso@gmail.com
Hi,
using mesa from git master (commit 76ba431b97087e2d5ca0351e0d613f0812fd1425), the mesa demo fp-tri, when running the scs.txt shader, displays the correct output overlayed by random blue-ish blocks (perhaps alpha channel corruption?).
The bug doesn't affect llvmpipe. Only scs.txt seems to trigger the issue.
This is on evergreen hw:
01:00.0 VGA compatible controller: ATI Technologies Inc Robson CE [AMD Radeon HD 6300 Series]
on an i7 machine with i386 debian unstable.
The bug is also present in the libGL 7.11.2 shipped by debian, so I don't think it's a regression or a bug in my config.
Please let me know if you need more info.
Thanks,
