Dear arch users, I'm using arch linux x86_64 (kernel 2.6.38), Firefox 5.0 and the Adobe Flash Plugin 10.3.162.29 64bit support (according to http://www.adobe.com/software/flash/about/). My problem is that I can view flash videos in Firefox in normal mode, but in full screen mode the videos slow down (and the CPU usage rises much). A half year ago everything worked fine, but after some updates it won't work anymore. I also tried a kernel/firefox downgrade without success. I suspect that it has to do with the hardware acceleration settings in the flash menu (right click on flash video). Here hardware acceleration is enabled and I can't disable it, since the mouse and keyboard simple don't work on the flash settings menu. Is there another way to disable hardware acceleration? Or any other hints? Thanks, Benjamin
