Bug ID: 108641 Summary: Interlaced dark lines in XCOM2 (UE3.5) on Aruba and Turks Product: Mesa Version: 18.2 Hardware: x86-64 (AMD64) OS: Linux (All) Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/r600 Assignee: dri-devel@lists.freedesktop.org Reporter: steelwinged@gmail.com QA Contact: dri-devel@lists.freedesktop.org
Created attachment 142355 --> https://bugs.freedesktop.org/attachment.cgi?id=142355&action=edit in-game screenshot
Game engine rendering outputs are interlaced with dark lines on r600.
Tested on: 7660G (Aruba) and 7670M (Turks) with Mesa 18.2.4. Renderdoc captures have been uploaded here: https://www32.zippyshare.com/v/G74cEAp5/file.html

--- Comment #1 from steelwinged@gmail.com --- If it's of any help, I have managed to narrow down the first output appearance of these interlacing lines between events glDispatchCompute(80, 45, 1) and second call of glDrawElementsBaseVertex(48).

--- Comment #2 from steelwinged@gmail.com --- Refreshing the upload due to the link expiring: https://www38.zippyshare.com/v/d0oWhmbR/file.html
Just a remark, the capture was taken with RenderDoc 1.1 and the bug still occurs on Mesa 18.3.1.

--- Comment #3 from steelwinged@gmail.com --- Situation still occurs on Mesa 19.1.3, refreshed RenderDoc capture at https://www47.zippyshare.com/v/fL6gXv7u/file.html
I might be conflating things, but there's also a shader scheduling error:
##post_scheduler: unscheduled pending instructions :MOV R27.x.5@R1.w, R17.x.1@R1.x MOV R27.x.3@R1.y, R17.w.1@R0.z MOV R17.x.1@R1.x, A9.y[R16.x.1@R0.w]_73F@R1.y rels: A9.y[R16.x.1@R0.w]_73F@R1.y : <= R9.y.1F, R10.y.1F, R11.y.1F, R12.y.1F, R13.y.1F, R14.y.1F MOV R17.w.1@R0.z, A9.x[R16.x.1@R0.w]_62F@R1.x rels: A9.x[R16.x.1@R0.w]_62F@R1.x : <= R9.x.1F, R10.x.1F, R11.x.1F, R12.x.1F, R13.x.1F, R14.x.1F MOV R14.y.1F, 4.2039e-45|00000003 MOV R13.y.1F, 4.2039e-45|00000003 MOV R12.y.1F, 7.00649e-45|00000005 MOV R11.y.1F, 5.60519e-45|00000004 MOV R10.y.1F, 4.2039e-45|00000003 MOV R9.y.1F, 4.2039e-45|00000003 FLT_TO_UINT R16.x.1@R0.w, C4102.x MOV R14.x.1F, 1.4013e-45|00000001 MOV R13.x.1F, 0|00000000 MOV R12.x.1F, 0|00000000 MOV R11.x.1F, 0|00000000 MOV R10.x.1F, 5.60519e-45|00000004 MOV R9.x.1F, 7.00649e-45|00000005
I don't read mnemonics, but I'm guessing that could be "Shader 9120" from the capture, which also causes the interlacing lines. I'm attaching it shortly.

--- Comment #5 from steelwinged@gmail.com --- Can confirm that the program with the attached compute shader is producing these lines, compared to nvidia.
