Whatever the solution, we need to be aware that a stylus can jump all over the screen but also move like a normal mouse cursor if it's in close proximity to (even not touching) the screen. The shell has no say in the movement then because the cursor needs to match the real-world stylus position, even when moving like a mouse.
I think that's the kind of device Qemu is emulating but also suspect Qemu's fake tablet is more complicated than that -- a mouse rather than a tablet, which emits absolute coordinates that can suddenly appear from any side of the virtual screen. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to mir in Ubuntu. https://bugs.launchpad.net/bugs/1670670 Title: Unity8 pointer does not stay in sync with Qemu VM tablet input Status in Canonical System Image: Confirmed Status in Mir: Invalid Status in mir package in Ubuntu: Invalid Status in qtmir package in Ubuntu: Confirmed Status in unity8 package in Ubuntu: Confirmed Bug description: Each time you login, or come back from the lock screen, you need to "recalibrate" the pointer by carefully moving the pointer into each corner. Contrast this with unity7, where the absolute position of the virtual tablet pointer is tracked, and sync is never lost.
