0000764: Minimizing in windowed mode causes entire window to be blacked out
While in window mode if you minimize (as opposed to alt tabbing) and maximize again, the whole window is black. The main game screen can be fixed by forcing the game to refresh the tiles (for instance, moving the viewport back and forth), or it does it on its own whenever a creature updates a tile.

However, the borders are exempt from this and remain black, as does the "FPS" portion of the FPS counter.
Open DF, minimize, then maximize.

This has occurred on two systems with drastically different configurations: a laptop on Wind7 off an integrated chip, and a desktop on XP running off of a proper GPU.
My programming sense suspects whatever calls "invalidate()" in the rendering engine is not being properly called on window focus after a maximize. In fact, I'm positive that's what it is, especially given the steps to fix it.

Marked as trivial as it's sure to die in the d# merge

Minor note here, when I used the windows shortcut to "minimize all windows", my Dwarf Fortress went away completely. I was able to see it in Task Manager and select "bring to front", then the taskbar had it listed again. The screen is all black, but like you said it's easy to bring back. I'm using PARTIAL_PRINT 0.
