--- Comment #2 from Sebastian Lackner sebastian@fds-team.de --- I also experienced the same rendering issues with FarCry 1 (needs a recent kernel, otherwise it crashes because of a kernel bug). Unfortunately it was not possible to reproduce the issue reliable, it only seems to happen with some specific probability, and after playing a while.
When comparing the terminal output I noticed a huge amount of fixmes like the following one, which were not present before:
fixme:d3d:wined3d_debug_callback 0x788ac90: "Program undefined behavior warning: Sampler object 3 has depth compare enabled. It is being used with non-depth texture 66, by a program that samples it with a regular sampler. This is undefined behavior.".
These tests were done a couple of days ago, so I don't have the full terminal output anymore. I'll try to repeat the tests and attach more logs, probably it helps.
