Bug ID: 97338
Summary: Black squares in the Spec Ops: The Line chapter select
screen
Product: Mesa
Version: git
Hardware: Other
OS: All
Status: NEW
Severity: normal
Priority: medium
Component: Drivers/Gallium/radeonsi
Assignee: dri-devel@lists.freedesktop.org

Screenshot showing the bug (frame 89)
With radeonsi the chapter select screen in Spec Ops: The Line has black squares
that should not be there. I have not observed this bug elsewhere in the game
(but haven't played through the whole game using radeonsi).
The number of squares increases with a higher texture quality setting. The
number and positions of the squares only changes when the camera moves.
The chapter select screen renders fine using the amdgpu-pro driver - tested
with version 16.30.3.306809 running on the upstream amdgpu kernel module.
Apitrace:
http://constexpr.org/tmp/SpecOps-radeonsi.trace.xz (70 MiB)
This bug seems to be caused by pixels with NaN values that make it into the
framebuffer and are extended to larger squares by a later post-processing pass:
After draw call 1441551, pixel (875, 573) of the COLOR0 attachment has RGB
components set to NaN.
GPU: R9 380X (tonga)
Kernel: 4.7.0-gentoo
Mesa: git-561fd22
LLVM: r278309
