Mouse cursor is black

[Fred]

Today I installed some update.
ia32-libs is marked as a transitional package, so I removed the transitional package after it was installed.

Then ubuntu installed lots of :i386 packages, so now I can run 32-bit apps and games.
But now the mouse cursor is some X Window System black cursor in 32-bit games, or at least is in the one I use (Tibia). Before it was the nice white one from ubuntu prior to this update.

I don't know exactly which package is responsible for messing up the mouse cursor.
