Summary: GNOME/Wayland desktop freezes when resizing Firefox
window

On Fedora 27 GNOME/Wayland desktop, I can reliably reproduce the desktop
freezing when grabbing the border of a Firefox window with the mouse and
dragging to resize. (Where Firefox brings Xwayland into the mix, IIUC. The
only way I found to make the machine responsive again is to ssh into it and
kill -9 the Xwayland processes, which gets me back to the GNOME login screen.)

The GPU is "VGA compatible controller: NVIDIA Corporation GF108GL [Quadro 600]
(rev a1)" according to lspci.
Reproducible with kernel 4.14.3-300.fc27.x86_64, but not reproducible with
4.13.13-300.fc27.x86_64.
Also not reproducible with neither (from a VT) running `weston --xwayland` nor
`weston --use-pixman --xwayland`.
