Problem description: Display corrupts, showing rectangular grid of tile-like thingies - this flickers on and off (seemingly) above the proper image. It is possible to keep playing, and even sometimes to make the corruption go away for a short time by eg quicksaving.
This has been a problem with 1A only, though Beta 1 made my extra monitor flicker so I had to turn that off.
I notice lots and lots of repeated "Debug Message: Popup Manager Update: Updating window with ID=32" at the end bit of the debug file.
FYI the debug.err from my last DA session has been mailed to gc2bugs@stardock.com
