The upstream bug was closed as wont fix and seems most distros reverted the
offending patch. Closing as wont fix.

Looks like Debian 9 will have Mesa 13 using LLVM 3.9.1, so it would probably be
affected.

I've been using Ubuntu 16.10 for several months without this issue.

On upgrade to 17.04, I was affected by this issue.

Here is the issue in Ubuntu's tracker:

Re Matt, comment #28, that setting can result in more time spent on shader
compiles. I don't think those are an issue in typical X server loads.

--- Comment #29 from Nicolai Hähnle  ---
It's almost certainly because we missed
01a133c760ebb8db1e204f76ba55c19558b1ce01 "AMDGPU: Do not clobber SCC in
SIWholeQuadMode" when back-porting -- probably because that one is not
straight-forward at all to back-port. The best course of action would indeed be
to revert that commit; IIRC it fixes a bug in Kodi, but the impact of that is
much less than widespread weird tints.

The part that really sucks is that I don't think an LLVM 3.9.2 is planned. We
need to keep an eye out on whether this causes a problem in any distribution
default installation.

FWIW, I haven't seen a problem in Ubuntu 16.10 even though it does have LLVM
3.9.1, probably because the default installation of Mesa is ancient.

Does this workaround have any negative consequences (e.g., performance
regressions), or is it suitable for use in a daily-driver environment?

I can reproduce this now. Setting R600_DEBUG=mono in the environment of the X
server works around the problem. I'm still trying to understand the exact
problem and why it wasn't caught by piglit testing.

I had the same problem with Gentoo Linux when upgrading from llvm-3.9.0 to
llvm-3.9.1: fbpanel icons exhibited a red shift. Reverting the above mentioned
commit against llvm-3.9.1 fixed the problem.

Debug logs for 3.9.0 vs 3.9.1-git-25e2616

Sure, Michel.

I didn't rebuild the last good commit. So I'm comparing 3.9.0 (from oibaf ppa)
with the first bad commit from 3.9.1 (25e2616). I hope that's close enough?

For each build, I've included both the stderr log using the R600_DEBUG envvar
and a screenshot of what Xephyr looks like.

Nicolai, please take a look.

Furkan, it might be helpful if you can attach the stderr output from Xephyr
with R600_DEBUG=ps when performing the same reproduction steps with a bad and
good commit.

AMDGPU: Fix an interaction between WQM and polygon stippling

Summary:
This fixes a rare bug in polygon stippling with non-monolithic pixel
shaders.

The underlying problem is as follows: the prolog part contains the polygon
stippling sequence, i.e. a kill. The main part then enables WQM based on
the
_reduced_ exec mask, effectively undoing most of the polygon stippling.

Since we cannot know whether polygon stippling will be used, the main part
of a non-monolithic shader must always return to exact mode to fix this
problem.

Does your problem disappear when you downgrade your LLVM packages to 3.9 from
here:
https://launchpad.net/~oibaf/+archive/ubuntu/graphics-drivers/+sourcepub/6850286/+listing-archive-extra

If you run dpkg -l | grep 3.9.1, I think that should get you the list of
packages that you'll need to download from that page.

I'm experiencing a similar issue after updating to the same packages. I ran
some tests last night, with Michel's suggestions on IRC. The problem goes away
when I build Mesa against LLVM 3.8. So the bug was most likely introduced
between with the LLVM update, going from 3.9.0 to 3.9.1rc3. Hopefully I'll get
around to bisecting it to find the offending commit.
