Hey,
I just recently upgraded from a 1920x1080 resolution monitor to a 2560x1080 one and the game seems to display everything correctly except for the campaign screen where the labour pool is displayed..
I've taken two screenshots to compare; You can see that on the top of the screen that the funds and debt etc. are not visable and on the botom the exit and results buttons are obstructed by the advanced buildings icons.

Hope this gets some attention. By the way, i have the same issue on Beta 5, 6 and 7.
Cheers,
B.
