Title:
  mouse pointer offset with gtk,gl=on

Status in QEMU:
  Confirmed

Bug description:
  When I turn gl=on for -display gtk, some Y offset is added to the
  mouse pointer coordinates. That is, when I click on an icon, an icon
  _above_ the one I clicked triggers.

  Using xev, it seems to be offset of 10-12 pixels.

  It happens with all ps/2 mouse, -usbdevice mouse and -usbdevice
  tablet.

  Without gl=on, the pointer is precise.

  I have these qemu versions:
  qemu-2.6.0-470.2.x86_64
  qemu-ipxe-1.0.0-470.2.noarch
  qemu-ksm-2.6.0-470.2.x86_64

  qemu-ppc-2.6.0-470.2.x86_64
  qemu-seabios-1.9.1-470.2.noarch
