https://bugs.freedesktop.org/show_bug.cgi?id=110635 --- Comment #8 from tempel.jul...@gmail.com --- Could we get an update on this? Apparently AMD_DEBUG=nodma makes the corruption completely disappear, so it seems the issue really is caused by asynchronous DMA. If the cause of the issue is not easy to find, perhaps disable async DMA by default? It doesn't seem to affect performance at all (at least not in wined3d and Gallium Nine) and it doesn't look like a good idea to me to have corruption in a vast number of games by default. -- You are receiving this mail because: You are the assignee for the bug.___ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel

https://bugs.freedesktop.org/show_bug.cgi?id=110635 --- Comment #7 from tempel.jul...@gmail.com --- The OGL issue occurs with both LLVM 8 and 9-git, so there might not be a connection to your radv issue here. I suppose LLVM 9 would also be fine with AMD_DEBUG=nodma & radeonsi, which indicates that the bug really is in the async DMA code of radeonsi (or at least triggers it). I also would suppose that RADV_PERFTEST= doesn't have to know the same values like AMD_DEBUG=, which afaik applies only to radeonsi. -- You are receiving this mail because: You are the assignee for the bug.___ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel

https://bugs.freedesktop.org/show_bug.cgi?id=110635 --- Comment #6 from Andrew Sheldon --- I get similar symptoms with Assassins Creed: Unity run under DXVK (with RADV). The issue doesn't occur with LLVM8, and seems to be a regression in LLVM9 since it worked fine with the last compile of LLVM9 I used (early May). The workarounds don't work in my case (nodma, zerovram) so it might be a separate issue.

https://bugs.freedesktop.org/show_bug.cgi?id=110635 Bug ID: 110635 Summary: briefly flashing corruption when playing various OGL games Product: Mesa Version: git Hardware: x86-64 (AMD64) OS: Linux (All) Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/radeonsi Assignee: dri-devel@lists.freedesktop.org Reporter: tempel.jul...@gmail.com QA Contact: dri-devel@lists.freedesktop.org I'm seeing briefly flashing corruption in various OGL games, mostly Dying Light and Counter-Strike Global Offensive Danger Zone. But I once also saw it in X-Plane 11. Happens with Mesa 18 and git and llvm 8 and git, but likely also even older versions in both cases. I was able to capture it by recording a video and then extracting an affected frame: https://abload.de/img/mpv-shot0001hkjyr.png Across the aforementioned games, the artifacts look akin or the same. Can also be brighter squares though. Hardware issue is unlikely, as radv / amdvlk never show this issue (and Windows driver neither). I fail to see a pattern when this corruption occurs, it seems like total chance to me while gaming. This is with an RX 580 on Arch. -- You are receiving this mail because: You are the assignee for the bug.___ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel
