Any text in desktop and menu is unreadable
Had the same problem after rejecting installation of HTC sense keyboard (I chose 'later'). Nothing seemed to help, until after some random opening and closing of apps (specifically, I went to messages) the app-choser had the icons visible again.
Went to settings on this menu, and simply exited settings and the problem was 'solved'. (not really solved of course, I don't know why it occured and it may happen again).

Btw: exactly that one: the HTC desire X!
