            Bug ID: 106594
           Summary: [radeonsi,regression,apitrace] Prison Architect
                    exhibits glitches

Compressed trace

I wanted to play Prison Architect again, but when I launch the game and during
gameplay there are sometimes triangles flickering over the screen in various
colours of the rainbow (see the first frame of the trace). And there are
actions that trigger these glitches reliably like opening the staff menu and
placing the mouse with a staff type selected over the map (see attached
screenshot or eg. Frame 599 in the trace).

This is a regression, because I was able to play Prison Architect with no
trouble in the past. However I cannot say whether this is a regression in PA or
in Mesa/LLVM, since it has been a while since I last played PA and there have
been updates to PA as well as the graphics stack. In any case I prepared a
trace (which looks a bit funny on reply: lots of black with the game window
stuck in the lower left corner of the replay), I'll attach as a compressed file
to this bug. I'll also attach the log from the game, there are couple of lines,
that seem interesting, like:
> ==OPENGL==> [location 'Bitmap::ConvertToTexture Before Texture Creation'] error code 0x502 (invalid operation)

While I'm using the "experimental VBO" feature of PA, turning that off, doesn't
fix this bug and thus seems unrelated.

This bug affects at least the Steam and the Humble Bundle builds of version
13f.

The graphics stack I used (fully updated Debian testing as a base) for testing
is:
GPU: Hawaii PRO [Radeon R9 290] (ChipID = 0x67b1)
Mesa: Git:master/6f558fb0f7
libdrm: 2.4.91-2
LLVM: SVN:trunk/r332816 (7.0 devel)
X.Org: 2:1.19.6-1
Linux: 4.16.10
Firmware (firmware-amd-graphics): 20170823-1
libclc: Git:master/a2118d58fc
DDX (xserver-xorg-video-amdgpu): 18.0.1-1

Let me know, if you need anything else.
