I searched for other cases of this error, but it looks like they were all many versions ago.

Graphics worked fine in Beta 2; recurring problem in Beta 3 where often the world map will not display; leaving me a gray screen instead. This is typically fixed by re-loading the game. HUD shows properly.

Anti-aliasing is off, tried running at minimum resolution with no apparent change.

No tactical battle map ever though; it is always gray. Reloading did not change. Occurred with several different battles and armies.

I don't know if its related, but Beta 3 has also been running REALLY slowly; where Beta 2 had not.

I'd chalk it up to just "oh, shitty laptop graphics card" if it hadn't all worked smoothly before the patch.

Running a Toshiba Sattelite L635 laptop
Win 7 64-bit service pack 1, Celeron 2 GHz processor, 2 GB RAM
"Intel HD Graphics" video card

I've got a screenshot, debug.err, and the save file available, if those are actually useful.

Now to go see if my desktop runs it better...
