Ubuntu Mini ToolBar causes problems

[ÄxxlForce]

I observed this issue for a while now but it got worse either with the latest VirtualBox updates or with upgrading from Ubuntu 14.04 to 16.04.

When the Mini ToolBar is activated for a VM there are two overlays being created by VirtualBox (each for every display see screenshot). These overlays seem to cause some problems:

sometimes they menus render on the wrong place on the display (only happens if menu is at the bottom)

sometimes unity (ubuntu's launcher) consumes clicks from the VM

since VirtualBox 5.1. when I switch Ubuntu workspace it instantly switches back to the workspace where the VM is running which is a show stopper for me

my workaround at the moment is to switch of the Mini ToolBar

Could the "sometimes unity (ubuntu's launcher) consumes clicks from the VM" bit be a duplicate of #15745?

no i don't think it's a duplicate.

i reproduced it and i got the following behaviour: sometimes when i switch ubuntu/unity workspace via shortcut "ctrl+alt+arrow key" and then click e.g. in the upper right corner of the guest it opens the menus of unity launcher. this used to be a lot worse because now this behaviour occurse rather rarely wheras it used to annoy me a lot in the past

maybe some more information about my workflow/setup

i always run my guests fullscreen on a two monitor setup. every time i want to "leave" the guest i use the "ctrl+alt+arrow key" shortcut to navigate to another workspace where i can work on the host. for this to work i disable "auto capture keyboard" in the VirtualBox preferences
