I've noticed what I believe to be the same bug: when moving the mouse around the vnc viewer, the guest does not seem to follow the same acceleration and I end up with 2 pointers completely out of sync. This makes it really hard to use the mouse (especially as the real pointer often moves off-screen before you reach the part of the guest screen that you need..) I normally would not care about mouse and UI (I run most guests in no-graphic mode), but I have to run some tests against "that-other-OS" at the moment, and this makes it even more of a nightmare. Any advice would be much appreciated. I have tried various VNC clients (no effect), looked for mouse options, etc..
