I've been experiencing some issues with PoM after having had my hard drive replaced. XQuartz appears to be completely impotent, despite having uninstalled and re-installed both PoM and XQuartz itself. When I try to open a program, XQuartz opens and turns the entire screen white, and the game doesn't open at all beyond that.
Debugging the issue gives me the following message:
