I'm experiencing the exact same issue as described in this post. The video from that post shows the same issues that I have.
Platform: Steam, no DLCs
OS: Linux
Version: v3.05.1186 -steam
Things I've tried:
Verified the integrity of game files in steam.
Deleted all saves, configs. Started new game.
Changed window resolution. Toggled Fullscreen/Windowed.
Pinned the game process to a single CPU core.
Messed around with in-game options.
What was the solution for gregmetz?
