The game runs fantastically overall, but there's some major issues going on with menus for me. After a mission has been running for a few minutes, things such as the tech tree, diplomacy menu, and even the save screen cease to display right (they work fine at first). At best, I'll get the menu with all of the text missing and the buttons not working, and at worst, the screen with freeze, but the game will continue as normal, and the buttons - assuming I can find them by randomly clicking where they should be - still appear to partially function.

Oftentimes this is accompanied by the software mouse icon freezing in place and the hardware icon appearing instead. Keyboard shortcuts still function when it's in this state, so I can close the menus with the ESC key, but after completing the mission, attempting to load the next mission will get me a black screen with nothing I can interact with (music still plays normally in the background). This does not apply if I fail the mission - while I still get a glitched results menu, I can usually find the "close" button and return to the campaign menu, which always displays correctly, and attempt the mission again, albeit with the glitched menus happening from the start.

Interestingly, this does NOT affect the objectives menu. That always works fine.

EDIT: If it helps, I'm running Windows 7 with a 1980x1080 monitor.

EDIT 2: Nothing? Nobody?
