    1 I confirm the above reports: this bug, which appears to be in the Win8/Win10 display driver installed by Guest Additions, still exists. I first encountered it after I transitioned from a Win7 Guest to a Win10 Guest, recently. When I first saw the bug, the display went to 800x600. I was able to increase the size in Win10, and currently my system changes the display from 1920 or 2560 pixels wide to 1600x1200. The system is usable, but it is a frustrating loss of functionality.

The Win10 system is usable, but this is a frustrating loss of functionality. As others have reported above, I confirm that normal full-screen operation can be restored by either restarting Win10 or by re-installing the Guest Additions.

    33I briefly thought that I had found a workaround, by always saving the state of the VM when not using it, but then I witnessed the bug occur immediately after restoring the state of the saved VM. I saw Win10 change to the reduced machine display size, and pop up a small temporary window informing me that the display driver was not responsive, and had been replaced. That failure of my hoped-for workaround prompted me to file this report. 
     
    55My Host is a MacBookPro running El Capitan 10.11.2, running VirtualBox 5.0.10 r104061, and my Guest is a 64bit 1cpu Win10pro v1511. I expect that the bug only depends on running a Win10(or Win8) Guest under VirtualBox 5, with the (faulty) VBoxVideoW8 display driver installed by VB5 Guest Additions.

    7 As others have reported above, I confirm that normal full-screen operation can be restored by either restarting Win10 or by re-installing the Guest Additions. 
     7NOTE: the ticket for this bug, as filed five months ago, says that it is for Mac hosts; that is probably wrong -- the bug probably occurs for ALL HOSTS.
