You could log in via ssh and get a screenshot using a command line utility, or you could take a picture of the screen.

Please attach the /var/log/Xorg.0.log file and the output of dmesg and glxinfo.

I tried taking a screenshot of the game running in windowed mode using the command `DISPLAY=:0 xwd -root | convert - /tmp/FILENAME`, but it only showed the game windows as all black. Any idea why this would be?

Anyways, I just took pictures with my phone of the same door in the foyer to the police building. The one to the outside is very dark/black and the one to the inside (presumably the same texture and physical model) is properly textured/lit.

Would you please record a trace using apitrace and send it to us? Thanks.

I can reproduce the issue on my Radeon HD 7950 (TAHITI) - here is an apitrace:

 http://constexpr.org/tmp/POSTAL2-radeonsi.trace.xz (75 MiB)

In addition to your Tahiti, Tonga is affected too.

*** Bug 91998 has been marked as a duplicate of this bug. ***

The apitrace is fixed for me with this commit:

acutiator, can you check if the bug is fixed for you as well?

I can't compile this right now as Mesa won't build for me on Fedora 22 using llvm from Rawhide. But I do have an extra Postal 2 game in my Steam inventory, so if anyone wants it so they can test this, I'm happy to provide it.

I do have POSTAL 2 myself and the it's fixed for me - just wanted to make sure we were seeing the same issue.

I have the exact same symptoms on Arch, RadeonSI, Mesa 12.0.1-7, on an R7 370, with the latest Steam version of POSTAL 2. I think there has been a regression.

I confirm same issue with Portal. Some textures have very dark lighting. With latest stable 12.0.1 all fine. Git version have this regression. Wine games have broken textures too (test on No One Lives Forever, Mesa 12.0.1 == ok, git == fail).

Can you check whether the resurfacing of this issue might be a duplicate of bug 97285? Just compile Mesa with attachment 125699 [details] [review] applied and verify that the issue persist if you use that version of Mesa. If it is fixed you should close this bug again and subscribe to the other because the original cause of this and the current problem would be different (even though the symptoms might be similar).

As Kai say, this bug duplicate of bug 97285. I check patch and apply it to fresh git and this fix it. So it can be mark as RESOVLED.

Dmytro Zverev, you are talking about a completely different bug in a different game.

This has indeed regressed as the fix was effectively removed in commit fe2d2c7ad8793fbcc4761cf5b51270c296eb811c
