Main window showing guest freezes after using virtualdesktop on Win7

Description
Host: Windows 7, running virtual desktop program Dexpot version 1.6.10, Build 2362. Host Video card: NVIDIA GeForce GTX 960 VirtualBox version 5.1.12r112440 (QT5.6.2)
Guest OS: KUbuntu 16.04.1
This behavior started after I just upgraded from VirtualBox version 5.0.?? to version 5.1.12.
When VB is in fullscreen mode, on the host I switch virtual desktops away from the desktop showing VB guest OS. When I switch back to the host virtual desktop the guest OS screen is frozen. HOWEVER, the VB preview window works. I can see applications switch, and can use a console to tell the machine to reboot.
The screen does not feeze if the VB guest OS is kept in Windowed mode (not full-screen mode). In fact, switching to windowed mode unfreezes the display.
The attached log is after the guest screen freezes, then I switch VB to windows mode to unfreeze the display, then switch virtual desktops on the host a couple of times.

I just upgraded to VirtualBox 5.1.14r112924(Qt5.6.2) and the problem is still present.

I, too, am experiencing this issue, since upgrading to 5.1.16. I was previously on 5.0.20 and have downgraded and can confirm the issue isn't happening there.
It appears to be just a video issue - the guest is receiving input. I.e., I switch desktops and come back, and I click on the guest and type, nothing happens. But if I switch away and back again in Dexpot, I see what I typed, although the guest is still 'unreachable'.

Well, we're now at V5.2.6 and the problem still remains. The only nice way for me to use DexPot and VB in full screen is to run an RDP session to the virtual machine. This causes many VPN clients to fail as they don't like RDP sessions.
Maybe one day someone will look into this.
