Bug Description

Yakkety, Mir-0.24, lp:miral

Run gnome-terminal on a touchscreen laptop and resizing by three-finger pinch...

$ miral-run gnome-terminal
$
(gnome-terminal-server:4817): Gtk-WARNING **: GtkSettings Cursor Theme: Unsupported GDK backend
...
(gnome-terminal-server:4817): Gdk-WARNING **: unknown property gtk-fontconfig-timestamp

(gnome-terminal-server:4817): Gdk-WARNING **: Ignoring unknown Mir event 11

(gnome-terminal-server:4817): Gtk-WARNING **: Allocating size to GtkBox 0x55eb906c6900 without calling gtk_widget_get_preferred_width/height(). How does the code know the size to allocate?
*** Error in `/usr/lib/gnome-terminal/gnome-terminal-server': double free or corruption (out): 0x00007f2e70258010 ***

(Can't reproduce with Mir-0.1, but that may be because resize was too broken.)

Actually, breaks just as easily with pointer based resize. (But I need an external mouse to get that to work.)

The problem seems specific to Yakkety: Can not reproduce on Xenial and Vivid+Overlay.

This appears to be racy code in the gtk-mir client: if I hack the server to only send one in five resize requests everything *appears* to work.

(Investigating to see if I can come up with a clean workaround based on this finding.)

Yeah seems to work on zesty. Although only as a regular user (not sudo) and with a mountain of GTK warnings.
