Having the same problem, happening on both stable and experimental.
Tried a clean install twice, didn't work. Neither did running the game through a different GPU.
Strangely you can temporarily fix it by creating a new Account on your computer and running the game on it, but that's less than ideal obviously. Dxdiag & Output log
Found a better temporary fix, since the issue is caused by the game being forced to run in a 154x0 window you should be able to fix it by putting
"-screen-width 1920 -screen-height 1080 " (or whatever resolution you want) into the launch options.
when i start the game (on mac) i get a green screen in stead of the water menu. i can still use the options load game, new game etc., but i can't see the back ground

I sent the devs an email about the bug too, hopefully they can see to it getting fixed!
