Bug 108194

This is actually another issue than bug 108111: I upgraded from Mesa 18.2.1 to 18.2.2. bug 108111 is fixed, but the characters are still displayed with these small black squares.

I couldn't reproduce. Do you think you could get an apitrace [1] of the problem?

Also if you were able to test 18.3 that would be great too.

It's also possible this is another example of bug #104602

I'm not sure for bug 104602 as everything else renders correctly.

---------------
I installed a fresh version of Ubuntu 18.04 on a specific disk and added padoka unstable ppa for mesa. I got this version:

1:18.3~git181021202700.2d235d6~b~padoka0

And the bug is still present. I also installed Ubuntu 18.10 (kernel 4.18), used the stock mesa (18.2.2), and the bug was there too.

---------------
I have two concerns about apitrace:
  1. the apitrace file will be full of copyrighted assets. Isn't there a legal risk to share such a file on the Internet?
  2. Civilization is a huge game and I'm afraid the apitrace file will be huge too (I need to reach the Leader screen before stopping the recording). What is the best way to share huge apitrace files with Mesa developers?

---------------
Maybe I could also enable some kind of error logging, or a dump of compiled shaders? By the way, the rendering level for Leaders is set to "low".

I'm back on my daily installation, with Mesa 18.2.3. In case in can help, here are my LLVM versions:

ii  libllvm6.0:amd64            1:6.0-1ubuntu2        amd64        Modular compiler and toolchain technologies, runtime library
ii  libllvm6.0:i386             1:6.0-1ubuntu2        i386         Modular compiler and toolchain technologies, runtime library
ii  libllvm7:amd64              1:7-2~oibaf~b         amd64        Modular compiler and toolchain technologies, runtime library
ii  libllvm7:i386               1:7-2~oibaf~b         i386         Modular compiler and toolchain technologies, runtime library

Possibly related to bug 104602. Can you try the workaround from that bug report.

To be clear. Can you right click on the game in steam, select properties.

Then click 'Set Launch Options'. In here add: R600_DEBUG=nir %command%

Click ok, and close the properties window. Then launch the game.

If I read this right Civilization VI in an OpenGL game?

Without shifting the focus to much have anyone maybe set EQAA filtering?
I've found an EQAA regression with TGSI and NIR running DiRT Rally on our Polaris 20.

Same corruption.
unset EQAA helps, here.
I've did some testing for Marek and Nicolai in April/May/June 2018 and have now to bisect.

I started both Steam and the game with R600_DEBUG=nir, it has no effect on the bug.

Graphics settings are all either "Low" or "Disabled", with the exception of v-sync. This includes anti-aliasing (thus no EQAA).

My system was slightly upgraded to kernel 4.20 and Mesa 18.3.3 (the bug is still here and looks the same).

Do you think you can test git master now that this fix [1] has landed?
