Xibo Player doesn't stay on top on Win7 SP1 with TeamViewer installed

The user has auto-hide enabled and set all notifications to Hide. If TeamViewer is uninstalled the problem goes away.

After 2 min xibo stops playing on top of screen, the taskbar is popping up in front of xibo. This is caused by notifications from the taskbar.
I disabled all the notifications but still no solution. Is this a known bug ?

Treating as a bug, but could do with some more examples of the problem.
