Title:
gnome-shell: stray configure notify event
Status in gnome-shell package in Ubuntu:
Incomplete
Status in mutter package in Ubuntu:
Incomplete
Bug description:
When unmapping X11 client, Gnome sends a stray configure notify event,
where 'y' has been moved up by the height of the window decoration.
Originally reported here: https://bugreports.qt.io/browse/QTBUG-71671
From xtrace output I see that gnome re-parents the window to the root
window and mistakenly adjusts 'y' coordinate. There are no plausible
reasons why WM should change window's coordinates when unmapping.
000:>:01c6: Event (generated) ConfigureNotify(22) event=0x02a00005
window=0x02a00005 above-sibling=None(0x00000000) x=600 y=526 width=200
height=200 border-width=0 override-redirect=false(0x00)
000:>:01c6: Event ReparentNotify(21) event=0x02a00005 window=0x02a00005
parent=0x0000011b x=600 y=526 override-redirect=false(0x00)
Where:
root window id = 0x0000011b
0x02a00005 = window which coordinates before calling unmap are x=600, y=600
