Created attachment 91729 [details] The capture for the window move bug Overview: Windows behind the toolbar can't be moved . Steps to Reproduce: 1) run weston-subsurfaces 2) Drag the drop the window behind the toolbar. 3) Can't move the window again.
You can move it with <mod> + left mouse button
Thanks for your advice, but i think the right solution is that make sure the window not to be behind the toolbar. I can move the entire window behind the toolbar by your advice, but also can't move it again, you can refer to my attachment bug_toolbar2.png.
