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

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

[Jirislaby]

Public bug reported:

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

This is because height from gdk_drawable_get_size() in gd_motion_event()
includes menu or whatever:

gl=off:
gd_motion_event: fbw= 640 fbh= 480 ww= 640 wh= 480 mx=  0 my=  0 x= 576 y=   3

gl=on:
gd_motion_event: fbw= 640 fbh= 480 ww= 640 wh= 506 mx=  0 my=  13 x= 571 y= 471

s->menu_bar's height is really 26px (506-480)
both s->notebook's and vc->tab_item's height is 506 px (the same as vc->gfx.drawing_area).

I cannot figure out why...

Ok, should we use
  gtk_widget_get_allocated_height and gtk_widget_get_allocated_width
instead of 
  gdk_drawable_get_size
?

[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.
