https://youtu.be/Vpi59ptOiyc Here is a video demonstrating the main issue. This does not show any lag but, it does show how VM doesn't capture the mouse correctly.
After capture if you move the mouse far enough off the VM window the mouse goes out of the window in odd places that isn't representative of the location of where the mouse is. The mouse will leave the VM from the middle of the of VM window at times. -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1808824 Title: Mouse leaves VM window when Grab on Hover isn't selected Windows 10 and Intel HAX Status in QEMU: New Bug description: On Windows 10.0.17134 I have been having the problem that the mouse will leave the VM window after a short time when grab on hover isn't selected. The VM will then try to grab on Hover and the mouse will grab in weird places and it will become very unwieldy to control the mouse in the VM window. This is exasperated by super slow response making it nearly unusable if the IntelĀ® Hardware Accelerated Execution Manager (IntelĀ® HAXM) is not currently installed on my machine. I know they are different things but they compounded on each other when you have a mouse that is not staying in the VM window and the VM's visualized cpu is acting VERY slow the system is unusable.
