terminalMoving

X process consumes imho too much CPU when running guest machine and doing basic users' actions on guest.

Host: F15 (qemu-kvm-0.14.0-4.fc15.x86_64, spice-server-0.8.1-1.fc15.x86_64)
Guest F15 (xorg-x11-drv-qxl-0.0.21-3.fc15.x86_64) with Gnome or KDE4 window manager.
Client F15 (spice-client-0.8.1-1)

I attach 3 profiles from sysprof tool.

1. OpenKWrite - opening KWrite on F15 guest with KDE4 as window manager.

2. TypingKWrite - trying to type in KWrite on F15 guest with KDE4 as window manager

3. terminalMoving - slow moving a terminal window on F15 guest with gnome as window manager.

qemu process hits 90-100% CPU usage while doing that actions on guest and Xorg process hits 60%-100% CPU usage on guest.

Note: First two profiles was provided by gracedman (John A. Sullivan).

Can you please provide your server log and run the server under valgrind (and 
provide that log).  Fixing the mime types of your attachments would be 
appreciated as well...

Mass closure: This bug has been untouched for more than six years, and is not
obviously still valid. Please reopen this bug or file a new report if you continue to experience issues with current releases.
