Vmware broker, PCoIP and weird behavior of published apps

We are experimenting with publishing apps, Vmware as a broker and over PCoIP as protocol.

Behavior:

Launch Word – launches fine but cannot minimize it to the task bar. When you do, you don’t see the desktop of the thin client – just black window.

If you press Ctrl+Alt+ down arrow you can see the desktop and Word minimized on the taskbar.

If you launch Powerpoint (after you've launched Word), it launches but it doesn’t create another “tab” on the taskbar – you have to click on the “Word 2016” to display Powerpoint. Basically everything you launch is “stacked” into the same tab on the task bar. Does not create separate windows or tabs for applications.
