Hi! With Wine Staging+DXVK some trees trembling instead of smoothly swaying from the wind. This does not happen with WineD3D or Windows.

Please, see here for more info:

It's sad, but Mesa developers ignore this bug report.

We are not ignoring, we are just busy with something else. I will have a look as soon as possible, don't worry.

Samuel, I do not agree with your decision to close this bug report.
If this bug was not in Mesa 18.1, but it appeared in Mesa-git 18.2, it means that some patch in Mesa-git 18.2 was added, which led to this regression. Therefore, if this regression will not fixed, it will later become part of the Mesa 18.2 stable version.
And so I think that it would be better to find the real cause of this regression instead of closing the bug report without fixing this bug.
Regards. Thank you.

Yeah sorry, I took the decision too quickly... Can you upload the savegame where you recorded the video please?

I already did this before I created this bug report. Please just follow the link, there are all these files.

Definitely not enough of caffeine today. Apparently, the issue is SI-specific which means I can't do anything because I don't have the hardware. It works fine on Polaris/Vega.

But, can I help you in any way? Or are we finally lost any hope?

Bisecting the issue can help.

And what do we need to do for this?

See https://bugs.freedesktop.org/show_bug.cgi?id=107156#c5
Comment 15 zefkerrigan 2018-08-26 12:09:45 UTC
I found out that this bug is only apparent when I compiled Mesa-git with llvm-svn installed.
But this bug is completely missing when I compiled Mesa-git with installed llvm 6.0.1 (stable version) .
And so what do I do? Should I open a bug report on llvm bugzilla?
Comment 16 Samuel Pitoiset 2018-08-26 13:13:20 UTC
No, I should be able to have a look in the next few weeks.

I guess this may not be the issue that is SI-specific which means this is apparently due to the fact that only those people who use Mesa compiled using LLVM 7 have this issue, but this issue is not present in those people who use Mesa compiled using LLVM 6.
Do you have any news about some any progress on the way to fix this bug?
Thank you.
