I first noticed this problem while running songbird v1.2 on Fedora 11. When I say hazy, try imagining yourself tuning a TV; that screen you get with nothing but grey and black static. This is the same thing I am experiencing. The only difference now is that I am running my own respin(made 29-august-2009, no songbird installed) KDE 4.3 and this only happens when using Firefox. Songbird and Firefox share a similar engine. No combination of keys works and I am forced to press my power button for 4 seconds to shut down and reboot. Can someone please tell me what is wrong.
