I've tested the game and could reproduce the issue with flickering triangles across the screen. I am attaching the patch which works around the issue for me. I tested on Nvidia, as well as the other reports here. It would be interesting to know how all that behaves on AMD.
The game is persistently sampling a texture which is attached as a render target at the same time. This is naughty. The patch issues a GL memory barrier before drawing for such a case which helps me on Nvidia. Yet it is not a good solution as it is still an undefined behaviour in OpenGL according to the spec.
