1: Congrats on launch! 2: Thanks for linux on day 1!
Now, the issue. I'm running a pretty standard linux setup (Ubuntu 14.04, updated proprietary NVidia drivers on a 570 card, etc.). I have 2 dell monitors running @1920x1080. When I start up the game, it seems to mis-detect them as one massive display, and ends up only drawing the bottom-eft 2/3 of the game on the main monitor (and nothing on the second monitor). The mouse cursor is also mis-aligned from what is detected for hovering - making it impossible to do much of anything.
If I disable multi-monitor, then it seems to start up fine.
