Surfaces that open underneath the cursor aren't aware the cursor is inside them until the cursor moves

[Robert Ancell]

Surfaces that open underneath the cursor aren't aware the cursor is inside them until the cursor moves.

This means that a toolkit like GTK+ wont correctly render elements like buttons to indicate they are active.

This could be solved by getting a motion event with action=hover-enter after the surface is created.

Quick analysis suggests due to QtEventFeeder/MirSurfaceItem this will will need a fix in both Qtmir and Mir

The qtmir side fix is pretty easy though I'd like to wait until after port-event-2.0 lands to not create conflicts/more work.

I'm not sure yet of how to handle the Mir side fix.

I don't think this is very important. In fact I recall having seen such bugs on other desktops too. It's fairly common and does not affect usability in any significant way.

Status changed to 'Confirmed' because the bug affects multiple users.

Syncing task from Mir.
