Hi, Some info on verifying this bug. As mentioned in the patch commit message I hit this problem while working on a spice agent for linux: http://cgit.freedesktop.org/~jwrdegoede/vdagent-linux/ To reproduce to the following: create a rhel kvm guest using the qxl adapter / spice protocol for display. and not using the usbtablet option for mouse. Inside this guest, compile the agent, then start vdagentd (as root) followed by vdagent Notice that you can now move your mouse outside of the spice-client window, even though it is active (iow grabbed) inside it. Now press the right mouse button on the desktop background and keep it pressed, this will give you a selection rectangle. Move the mouse slowly around a bit keeping the button pressed, notice that the corner of the selectionrectangle exactly matches the hotspot of the mouse corner. Now move the mouse around fast. After a while you will see the actual mouse position and the corner of the selection rectangle no longer match. This is caused by the bug this patch fixes. ### Alternatively, I can verify the fix myself. Once a fixed kernel is available it is easy for me to install it inside my guest and verify this problem is not happening, exp. as I exactly now the problem symptoms. Regards, Hans
