Bug ID: 100802 Summary: [regression] mostly blank graphics on Faeria Product: Mesa Version: 17.0 Hardware: Other OS: All Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/radeonsi Assignee: dri-devel@lists.freedesktop.org Reporter: tjaalton@ubuntu.com QA Contact: dri-devel@lists.freedesktop.org
Running free-to-play Faeria from Steam on Ubuntu the opening graphics shows only the login window, background is totally blank. Mesa 12.0.6 was fine, 17.0.4 is not.
Tested on R7 260X (Bonaire), i965 is working fine with both Mesa versions.

--- Comment #1 from Timo Aaltonen tjaalton@ubuntu.com --- still there in 17.1-rc2
https://bugs.freedesktop.org/show_bug.cgi?id=100802
--- Comment #2 from Timo Aaltonen tjaalton@ubuntu.com --- happens on debian stretch too with mesa 13.0.6

--- Comment #3 from Timo Aaltonen tjaalton@ubuntu.com --- Ran more tests and tried to bisect mesa, but the end result is something weird that I can't figure out anymore where the bug is. Using whatever combination of kernel, llvm, mesa, or the radeon X driver on Ubuntu 16.04 seems to work, but fails on 17.04.
Took an apitrace of running Faeria: https://aaltoset.kapsi.fi/tmp/Faeria.x86_64.trace.xz

--- Comment #4 from Timo Aaltonen tjaalton@ubuntu.com --- Backporting the full X stack (including kernel 4.10, xorg 1.19.3) from 17.04 to 16.04 didn't break it, so looks like the breakage is due to some compiler issue on 17.04? That sounds like a treat to track down..

--- Comment #5 from Michel Dänzer michel@daenzer.net --- FWIW, the apitrace plays back fine for me on Kaveri, with radeonsi from Mesa Git master built using
-fno-math-errno -fno-trapping-math -O3 -fno-omit-frame-pointer -ftree-vectorize -march=amdfam10 -mtune=native
for optimization with
gcc version 6.3.0 20170415 (Debian 6.3.0-14)

--- Comment #6 from Samuel Pitoiset samuel.pitoiset@gmail.com --- Same here, the trace replays fine with Mesa/LLVM from today on RX480.
