    @LostInSpacetime: your bug might be in fglrx, or it might be in Skype... Try using Skype without fglrx (use the FOSS ati/radeon/radeonhd driver) to see if you can reproduce the bug.
    You can also try disabling composite in fglrx (it doesn't deal well with it).

    @mirv: there is one major difference between your Nforce3 chipset and mine: Nforce3 uses AGP (which is now old enough to have all quirks known and worked around), while Nforce430 (mine) and more recent (baskin) use PCI-express. I suspect the problem is to be found in fglrx's internal, proprietary, graphics bus controller: PCI-E being still evolving, I betcha there's a little regression in it somewhere!

    One path worth investigating: how does fglrx deal with PCI-E 2.0 cards plugged in PCI-E 1.0 motherboards? Did it change in any way for Catalyst 9.9?

      My mistake in numbering of nforce - I do use a PCI-E card, a radeon3650 from sapphire to be exact.

        Ah. Well then, it's something else. What chipset are you using exactly?

          I'll post details later tonight if I remember after work.

          -- ok I use an asus m2n-e motherboard (nforce 570 or something like that). Apologies, I had confused my old computer previously, which used an nforce3 (this is what happens during crunch time at work, you mix up strange things). Kernel is 2.6.32-gentoo-r1, catalyst 9-11, AMD64 X2 3800+, radeon 3650. Obviously I use gentoo 64bit. xorg-server is 1.6.4. Let me know if you'd like more details.

            I tried some things. The bug does only appears with fglrx and compiz(or metacity with compositing)+xv. If I force skype to use x11 instead, the video window works as expected. The problem with x11 is just that it's slow and doesn't scale (with skype).

            So it seems it's a fglrx bug affecting xv+compositing.. at least on my hardware (HD3200)

              Mine is a NVIDIA? nForce 750a SLI Chipset.

                Well, I use Mandriva 2009.1 (I also tried 2010.0) with kernels 2.6.29.6 and 2.6.31.5 (2009.1 backported 2010.0's kernel) with xorg-server 1.6.4/1.6.5 in 64-bit. It seems that kernel and Xorg versions have no real impact on the bug, however all our builds are 64-bit.
                We lack statistical evidence; from what we're getting here, 2 out of 4 Nvidia chipsets, of varying ages, got us a failure, the only AMD chipset succeeded with a kernel/server/card combination that failed on an Nvidia-based mobo. More reports would help (but we're not finding any).
                This could be a combination of things:
                - an Nvidia chipset
                - with a certain BIOS version
                - and certain cards
                may cause failures.

                I'd love finding an updated VBIOS for my card; the one it's using is shared by several early 4850 manufacturers; some updated their BIOS, but not all did; and I don't feel like experimenting with BIOSes I didn't modify myself

                Now though, I'd like to add some things:
                - my previous motherboard was made by Asus, a company that is tepid at best towards Linux (and at the time I bought the mobo, didn't acknowledge its existence), while my current one is from Gigabyte (first mobo maker to support LinuxBIOS officially on one of its products).
                - my previous mobo used a beta BIOS: I didn't feel like downgrading it to the latest 'official' BIOS, a previous experiment having me computerless for weeks when I had to have the BIOS chip re-flashed, and which was hardly supposed to help.
                - my previous mobo saw four years of heavy use; although no capacitors leaked and it passes all RAM and CPU tests, I did have overheating problems with this system at times, and it may not be considered rock stable anymore.

                  Think youre right that one ATI card will work but that the Nvidia chipset will not support Crossfire.

                    The 9.12 driver brought notable improvements in card initialization routines; while I won't rebuild my previous rig to test, I wonder if the bug still exists.

                      Where can I download the Linux version of atiflash?
