Bug description:
Impact
------
The pointer's depiction (i.e. arrow, hand etc.) becomes stuck in
Wayland GTK core22 snaps after using the mouse to drag stuff in that
window.
Test plan
---------
This test plan involves moving the mouse pointer around a lot. Do not
let the mouse pointer leave the window, unless directed otherwise.
+ Reproduce the bug:
++ Start the Gnome Wayland session (Ubuntu's default);
++ snap run firefox;
++ Select text (say, from the bug's title);
++ Now drag the text. More specifically:
+++ Move the mouse pointer over that text;
+++ Click button1, move the mouse outside the selected text area, and release button1;
++ Click button1 to unselect the text;
++ Move the mouse pointer over some text;
!!The mouse pointer does not become a beam, but it should;
++ Move the mouse pointer over a link;
!!The mouse pointer does not become a hand, but it should;
+ Install these packages from proposed:
gir1.2-mutter-16 deb introspection optional arch=linux-any
libmutter-16-0 deb libs optional arch=linux-any
mutter deb x11 optional arch=linux-any
mutter-common deb misc optional arch=all
mutter-common-bin deb misc optional arch=linux-any
+ Log out;
+ Verify the bug is fixed:
++ Start the Gnome Wayland session (Ubuntu's default);
++ snap run firefox;
++ Select text (say, from the bug's title);
++ Now drag the text. More specifically:
+++ Move the mouse pointer over that text;
+++ Click button1, move the mouse outside the selected text area, and release button1;
++ Click button1 to unselect the text;
++ Move the mouse pointer over some text;
!!The mouse pointer becomes a beam, as it should;
++ Move the mouse pointer over a link;
!!The mouse pointer becomes a hand, as it should.
Where things could go wrong
---------------------------
In mouse pointer events, particularly dragging/dropping with the
mouse, when using the Gnome desktop environment.
