Aapo: could you have a look at mangband (mangband.org)? It's a multiplayer variant of angband. It does compile, though quite a lot of warnings show up. Still, X11 seems to be the problem. Game starts, pulls a list of servers available, allows selecting race/stats/class but after logging in and splash screen from the server it crashes (starting map shows up for a pico-second):

X Error of failed request: BadValue (integer parameter out of range for operation)
Major opcode of failed request: 137 (MIT-SHM)
Minor opcode of failed request: 3 (X_ShmPutImage)
Value in failed request: 0x1e2
Serial number of failed request: 631
Current serial number in output stream: 632

Tried ./configure --disable-x11, but it doesn't seem to change anything. --disable-sdl version crashes instantly.
