I'm seeing two different behaviours depending on the guest:
The first is the traditional behaviour where you click in the window, it
grabs and you control the guest's mouse cursor, and here ctrl+alt works
fine to ungrab.
The second one is much like with the tablet in that it shared the mouse
cursor between host and guest. In this one, when I ungrab with ctrl+alt,
it automatically grabs again as soon as I move the mouse cursor (i.e. it
is actually ungrabbed if I only use the keyboard). But as the mouse
cursor is shared with the host, I can simply move it out of the VM
window and then the capture ends, so that's fine.
So for me that's exactly what I want it to do (RHEL 7 host with qemu.git
master). Is what you got the second behaviour, but without the shared
mouse cursor?
