Ever since my last reboot, the game Heroes of Newerth no longer renders any fonts or cursor, but otherwise runs fine.
The updated in that time period:
libxcb and lib32-libxcb
Any ideas on how I can fix this?
I think libxcb/lib32-libxcb (the latter if HoN is 32bit) are the only updates that might cause such a problem so you could try downgrading those and see how it goes.
That was my original thought. I managed to downgrade the 64-bit libxcb, seeing as my HoN is 64-bit anyways, but that didn't fix the problem either. I'm really stuck here.
