[Bug 1793859] Re: GTK display and mouse input area scaling fails when using vfio-pci device

[Thomas Huth]

The QEMU project is currently considering to move its bug tracking to
another system. For this we need to know which bugs are still valid
and which could be closed already. Thus we are setting older bugs to
"Incomplete" now.

If you still think this bug report here is valid, then please switch
the state back to "New" within the next 60 days, otherwise this report
will be marked as "Expired". Or please mark it as "Fix Released" if
the problem has been solved with a newer version of QEMU already.

Thank you and sorry for the inconvenience.

Title:
  GTK display and mouse input area scaling fails when using vfio-pci
  device

Status in QEMU:
  Incomplete

Bug description:
  Version qemu 3.0.0-1 running on Arch. Found on Windows 8.1 and Windows
  10 VM's when using Intel gvt-g device.

  While in fullscreen the GTK display is scaled larger than the x11
  screen or virtual machine resolution. Without choosing zoom-to-fit
  portions of the VM display are not shown on x11 screen regardless of
  the VM resolution. When zoom-to-fit is done the mouse that's shown on
  screen and actual input are off sync. The mouse can wander off screen
  when going left and down.

  This message is shown when changing from gxl-vga to vfio-pci in view menu.
