[b29] Game screen doesn't update w/ new character

[CaptainTrips]

After starting a new character, I am able to 'play' - i.e., I can move, see game messages in the log, etc. - but the actual graphics just remain static. I can almost always fix this by reselecting my tile size (I assume it's the "resetting" of the graphics that fix it) or quitting and loading.

I can get this to happen... sometimes. Doesn't always happen, but when it does those "solves" fix the problem. Minimap updates just fine though.

It appears that turning off framebuffers fixes this entirely - but at the expense that the entire game looks much worse. Better to just restart the game once in awhile than have blocky shadows.
