Thanks, I suspect this is a dup of bug #503156, but I'll leave it open until we can confirm that for sure Is there anything I can do to help debug this - this is a major problem, rendering guests pretty much useless for me. What I've found so far: * It is qemu-kvm specific - does not happen with -no-kvm * It is cirrus specific - does not happen with -vga std * It worked until kvm-83 - stops working at kvm-84 I'll keep debugging this. Glauber posted a patch here: http://lists.gnu.org/archive/html/qemu-devel/2009-07/msg01498.html Looks like it's confirmed as a dup of bug #503156, so marking it as such *** This bug has been marked as a duplicate of bug 503156 *** |
Created attachment 349096 [details] Screenshot of Windows XP running in a guest Description of problem: When running a (Windows XP) guest under qemu-kvm viewed using a vnc viewer it seems that the display is not updated properly when scrolling windows resulting in unreadable tearing and garbage being displayed. Screenshot attached. This is a regression from the F-10 packages where this problem was absent. I see the problem with both the vinagre and virt-manager vnc client. Version-Release number of selected component (if applicable): qemu-common-0.10.5-3.fc11.x86_64 qemu-system-x86-0.10.5-3.fc11.x86_64 qemu-img-0.10.5-3.fc11.x86_64 virt-manager-0.7.0-5.fc11.x86_64 libvirt-python-0.6.2-11.fc11.x86_64 libvirt-0.6.2-11.fc11.x86_64 python-virtinst-0.400.3-8.fc11.noarch vinagre-2.26.2-1.fc11.x86_64 How reproducible: Every time Steps to Reproduce: 1.Start a windows XP guest and connect via vnc 2.Scroll an application 3. Actual results: Garbage on screen Expected results: No garbage on screen Additional info:
