Traces and hacked shader
The game plays fine under wine, but in a certain stage the player and enemies
are invisible.
There is a semi-official hack for this problem, involving a changed shader.
(See attachment):
<span class="quote">> //gl_ClipDistance[0] = dot(gl_Vertex, ClipPlane);</span >
Two apitraces included, with the hack and one without.
A few more things:
- Some windows machines have the same issue, but most seem to run the game just
fine
- The trace I made doesn't replay fine on my win10 either (AMD driver issue or
maybe wine making broken opengl calls?)
I'd test with wine and proprietary drivers on my linux, but can't get them to
work.
Since I don't know what's wrong here, I hope you can help me shed a light on
this - wheter it's an actual mesa issue or just a broken game.
System:
Arch Linux x64
Using mesa 18.2.0
Linux 4.18.7, amdgpu
Radeon R9 285</pre>
