I have just made a new box as my existing Linux Box is struggling. It is an ASUS M4A79XTD Mobo, Athlon 11 x3, 4GB Mem, MSI NX8600 Graphics. I decided to try the 64 bit version of Open SUSE 11.4 as the OS.
I have used the 32 bit version of SUSE 11.2 on my old box for some while & have been very pleased with it, no problems.
The SUSE 11.4 64 bit works very well, I have installed all the necessary extras as recommended by Jem with his Perfect Desktop, although he does not yet have a 11.4 version, I used his 11.3 version of Perfect Desktop as a guide.
The only problem that I have found so far (1 days use) it is a very annoying one, is that when playing a streaming video eg a Utube video, there is a flickering small white square in the middle of the picture, the progress bar flickers & is unsteady, & worse of all if I click on the Full Screen icon the video stops completely.
I seem to have the correct Xorg & nVidia drivers installed & the system is up to date with upgrades. Playing a film or an AVI video file is no problem full screen or not.
Could this be a problem with the 64 bit OS, or SUSE 11.4, I have never experienced this problem with 32 bit SUSE 11.2 & previous.
Any ideas, help, solutions, would be very welcome.

I turned off, waited for some minutes & rebooted, on boot a nVidia logo appeared, must have loaded a driver, now full screen is OK, but my lost workspaces are still gone.
