Workaround: Use mir_proving_server which does not have this bug. Because it doesn't require that resizing occur while the cursor is inside the app window. This is related to the "aura" feature detailed in Trello.
** Changed in: mir (Ubuntu) Status: Invalid => Triaged ** Changed in: mir (Ubuntu) Importance: Undecided => Medium ** Description changed: mir_demo_server(_minimal) version 0.13 and later: Window movement/resizing stops responding when the cursor leaves the surface. If you move or resize a surface with Alt+(button1/button3) then it's very easy to get the shell into a state where the window stops - responding to movement/resizing and even becomes unrecoverable. + responding to movement/resizing and even becomes unrecoverable (window + 1px wide). Essentially the problem is the shell is only looking at the current cursor position and doesn't do anything if it's outside of the surface. This is frustrating as waiving the mouse around a bit it's very easy to reach this situation. It should be looking at the gesture as a whole and only doing position checking at the start of the move/resize gesture (ie. mouse button down). Thereafter the gesture should be continuous until the button is released, regardless of whether the cursor is still inside the surface/titlebar. You will find this is how all real desktops work, and mir_proving_server tries to too. Surfaces should always "own" input regardless of cursor position, just so long as the gesture (mouse down) began on that surface. The "unrecoverable" bit: This happens if you resize a surface too small/thin and it becomes impossible to resize it bigger again. ** Summary changed: - mir_demo_server(_minimal): Window movement/resizing stops responding when the cursor leaves the surface + mir_demo_server(_minimal): Window movement/resizing stops responding when the cursor leaves the surface, and can lead to windows 1px wide and unrecoverable. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1447886 Title: mir_demo_server(_minimal): Window movement/resizing stops responding when the cursor leaves the surface, and can lead to windows 1px wide and unrecoverable.
