            Bug ID: 102885
           Summary: regression - 17.2 sparkle grid in shadows
           Product: Mesa
           Version: 17.2
          Hardware: x86 (IA32)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/Gallium/radeonsi
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: darktjm@gmail.com

Ugly shaded areas

See attached image.  While I was retesting many games in wine, I noticed that
multiple games, when run in wine, show black background with dot grids instead
of alpha blending, apparently.  Reverting to 17.1.x fixed this.  I haven't the
patience or continuous power to my machine to git-bisect; the only thing I can
help with is that it doesn't do this with LIBGL_ALWAYS_SOFTWARE=1, so it's
likely a radeonsi bug rather than mesa core.

Hardware:
    Device: AMD Radeon R7 Graphics (AMD CARRIZO / DRM 3.18.0 / 4.13.2-gentoo,
LLVM 5.0.0) (0x9874)
OpenGL renderer string: AMD Radeon R7 Graphics (AMD CARRIZO / DRM 3.18.0 /
4.13.2-gentoo, LLVM 5.0.0)

Note that this has been broken since the earliest rc I tried, also with earlier
releases of the kernel and llvm, firmware from both before and after 06 Sept.

Apologies if this has already been reported; I can't really tell and it has
been broken now for at least all rcs I've tried, 17.2 release, and 17.2.1.

Can you record a trace with apitrace that reproduces the issue?

If not, which games are affected? What Wine version? Is CSMT enabled?

> Can you record a trace with apitrace that reproduces the issue?

I could, I guess.  I've never used the tool before, though, and have no idea
how to trim it to the relevant part.  I can't attach a 179MB trace file (109M
compressed).   I tried trimming to just the relevant region(s), but it's screwy
at best, and mostly garbage in the replay, I doubt it's useful.

> If not, which games are affected? What Wine version? Is CSMT enabled?

I dunno.  I erased my notes after I discovered at least 4 broken games; at that
point, I realized that these problems only started around the later tests,
where Mesa had been auto-updated to 17.2-some rc by my regular system updates,
so I stopped blaming wine and tried reverting Mesa instead.  The only ones I
still remember are KOTOR (because it was worst) and Chains of Satinav.  The
attached picture is from the former; I test the presence of the bug using the
latter, because KOTOR often has (unrelated) trouble starting up.  Note that
neither game shows this problem all the time:  Satinav only shows it in the
cursor when the cursor is over a selectable area, and KOTOR only shows it at
certain viewing angles (I don't really know what the difference is).  Both, and
others that had issues, displayed brief flashes of dot grids at various other
times as well.  I currently use Wine 2.0.2, 2.15, 2.15-staging, and
with/without gallium-d3d9.  I can assure you that I tried all combinations of
the above when I discovered it didn't work normally.  2.0.2 doesn't use csmt by
default, and 2.15 does, so apparently csmt doesn't make a difference.

Yeah, please upload the trace somewhere. You can use dropbox or some other
similar services.

I said I wouldn't, but I went ahead and did a git-bisect:

878bd981bf7aac1466ba3278796f200fa329e2af is the first bad commit

If I have an opportunity later today, I may upload the trace file somewhere.

I'm not sure I trust dropbox entirely (it's a bit invasive), but I went ahead
and created an account to upload the trace file:

https://www.dropbox.com/s/uo6kllmpr1b5jrt/satinav.trace?dl=0

This is from Chains of Satinav.  The sparkle grid appears in the large cursor
in the middle of the screen when it's hovering over the ship's window. 
Normally it is grayish with a wave pattern over it, but when broken, it's just
a sparkle grid.  Please let me know if/when you're downloaded it, so I know it
worked, and I can delete it.

Note that I got a trace from KOTOR as well, but it is not usably replayable,
unlike this one.

Thanks for the trace (and the bisect), I can reproduce the issue.

A temporary workaround is to use R600_DEBUG="nodccfb".

Does the existence of this workaround mean you do not intend to fix the bug? 
Given that there have been 2 17.2 releases (and 17.3 is in rc2) since this was
written, and the bug is still present, I guess so.  Gentoo is making it really
hard to retain my own workaround (don't upgrade to 17.2) due to its dependency
on llvm-4, so I guess I'll just have to live with your workaround.

No, the bug should be fixed. I just didn't have much time to work on it to be
honest.

OK, no hurry.  It's not like it's corrupting memory or anything, and the
workaround does work.  I was just concerned it would never be fixed.

Deleting the trace means no one else can investigate the bug. Is this still a
problem?
