Bug ID: 93591 Summary: [TONGA] ARK Survival Evolved: corruption of main menu textures Product: Mesa Version: git Hardware: Other OS: All Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/radeonsi Assignee: dri-devel@lists.freedesktop.org Reporter: EoD@xmw.de QA Contact: dri-devel@lists.freedesktop.org
Created attachment 120812 --> https://bugs.freedesktop.org/attachment.cgi?id=120812&action=edit apitrace trace
I get flickering textures on buttons in the menus of ARK Survival Evolved on my Tonga.
A video of the corruption: https://www.youtube.com/watch?v=29OP-wlashA
$ glxinfo | grep OpenGL OpenGL vendor string: X.Org OpenGL renderer string: Gallium 0.4 on AMD TONGA (DRM 3.1.0, LLVM 3.8.0) OpenGL core profile version string: 4.1 (Core Profile) Mesa 11.2.0-devel (git-14f21f5) OpenGL core profile shading language version string: 4.10 OpenGL core profile context flags: (none) OpenGL core profile profile mask: core profile
I am using the current kernel "4.4.0-rc3-geafbbd9" from cgit.freedesktop.org/~agd5f/linux/log/?h=drm-next-4.5 with powerplay enabled.
This issue does not appear on llvmpipe (neither in the apitrace replay, nor with the game).

--- Comment #3 from Nicolai Hähnle nhaehnle@gmail.com --- Based on an analysis of the trace I've done some time ago this is a pixel discard problem, most likely the same as bug #93594.

I am not surprised, thanks for looking into it :)

--- Comment #5 from Nicolai Hähnle nhaehnle@gmail.com --- So, I've looked into this again out of curiosity, because I do have an LLVM patch that can be used to work around this. However, the patch introduces some inefficiencies, and this is a game bug: it is clear from playing with the provided apitrace that a derivative is taken after a non-uniform discard/kill, which is undefined behaviour in GLSL.
Does anybody paying attention to this bug report know of a way to contact the game developer about this?

Unfortunately there seems to be no bugtracker. The list of (core) devs can be found on their homepage http://www.instinctgames.com/#c-about-us together with email info@instinctgames.com and phone +20222913556 though.
They are apparently also use Twitter: https://twitter.com/instinctgames Facebook: https://www.facebook.com/InstinctGames Linkedin: https://www.linkedin.com/company/instinct-games
I could find the linkedin profile of one of the graphics engine programmers too: https://www.linkedin.com/in/mohammad-yusuf-2b7531a7
