+mouse pointer offset with gtk,gl=on
+
+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-kvm-2.6.0-470.2.x86_64
+qemu-ovmf-x86_64-2015+git1462940744.321151f-2.1.noarch
+qemu-ppc-2.6.0-470.2.x86_64
+qemu-seabios-1.9.1-470.2.noarch
+qemu-sgabios-8-470.2.noarch
+qemu-tools-2.6.0-470.2.x86_64
+qemu-vgabios-1.9.1-470.2.noarch
+qemu-x86-2.6.0-470.2.x86_64
+
+The same happens with qemu from git, commit a28aae041aa76a779df6467a7fe68b9e8a8b2c0a.
+
+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
+
+
+Yeh I saw this behaviour as well.
+
+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
+?
+
+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.
+
+Mouse still doesn't work properly with 2.9.0 and Ubuntu 17.04 guest
+-smp 2 -enable-kvm -vga virtio -display gtk,gl=on -m 2048 -cdrom ubuntu-17.04-desktop-amd64.iso
+
+mouse works better with debug & fix patch 
+
+seems to be fixed with f1aba960cc40ab65fa88c8678883bd2201708c55 : https://git.qemu.org/?p=qemu.git;a=commit;h=f1aba960cc40ab65fa88c8678883bd2201708c55
+
+
+anyone else can confirm, i have another issue affecting scaling with my setup.
+
+FWIW: Commit f1aba960cc40 has been released with v3.1.0.
