I'm using fedora linux and have tried version 5.42.0 and 6.3.0 on a thinkpad x220t with a i7-2620m and 8gb's of ram.
Whenever I press to go fullscreen within the e-book viewer it becomes a non-existent program, even though it shows up as a program it is see-trough / just not showing.

Anyone know how to fix this?
