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.

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.
