[Qemu-devel] [Bug 1592351] Re: mouse pointer offset with gtk, gl=on

[Jirislaby]

That works for scale = 1. Given scale is set only in draw (2d) and not
in render (3d), it never worked with other scales. Apart from that, the
code is full of bugs.

I could make it work with the attached diff modulo the fprintfs,
basically. However I am not going to invest more time into that, as it
has to be audited and fixed by someone who actually understands the
code.

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:
