Crash when going fullscreen or restoring

[Thomas Astleitner]

When I restore a fullscreen session to have the window frame or vice versa by the usage of HOST-F, the guest crashes frequently. Using Windows XP x86 on a Windows XP x86 host.

I also get this problem.

Windows 2008 R2 guest instantly crashes with no error message when using Ctrl+F to exit full-screen. Crash occured on VB 4.2.4, and also on 4.2.6.

Host has monitor 1 portrait 1050x1680 and monitor 2 landscape 1280x1024, as does guest.

Using host video driver command (hot-key) to switch monitor 1 to landscape, and guest auto-switches to landscape also. Using host video driver command (hot-key) to switch monitor 1 to portrait, and guest auto-switches to portrait, BUT has the wrong size : should be 1050x1680 but instead selects 1400x1050, with the right-most 350 pixels not visible on the main monitor. Using guest display properties to change resolution to 1050x1680 works. Ctrl+F causes instant guest crash.

I also note that on the affected VM, VB menu View > is missing options "Switch to Fullscreen", "Switch to Seamless Mode", "Switch to Scale Mode", "Auto-resize Guest Display".

The View menu only has "Virtual Screen 1" and "Virtual Screen 1" menus.

An XP VM (having only a single monitor) on the same host is OK and does not have the crash problem, regardless of which monitor it is moved to.

Adding a second monitor to the XP VM, and then it also has the crash problem with Ctrl+F.

I've been seeing this problem as well. Posted my full scenario in the forum at ​https://forums.virtualbox.org/viewtopic.php?f=6&t=54144.

My eventlog entries also match what is listed above.

There were some fullscreen fixes in 4.2.8 and 4.2.10. Could you check if this problem persists for you with VBox 4.2.10?

[Mark Cranness]

Still a problem with 4.2.10

With 4.2.8 : Taking a snapshot caused monitor 1 on the VM to blank (display black except for the VirtualBox toolbar minimised at the top of my screen), but View > Virtual Screen 1 > Use Host Screen 2 and back again made it visible again.
Host+F to exit full screen was OK, but Host+F to enter full screen crashed as before.

Event Log:

Faulting application name: VirtualBox.exe, version: 4.2.8.0, time stamp: 0x5124ed82
Faulting module name: VirtualBox.exe, version: 4.2.8.0, time stamp: 0x5124ed82
Exception code: 0xc0000005
Fault offset: 0x00000000000d1ad6

With 4.2.10 : Taking a snapshot was OK.
One test went: Host+F to exit full screen was OK, but Host+F to enter full screen crashed.
Another test went : Host+F to exit full screen crashed.
(All attempts to enter fullscreen fail.)

The crash is fixed, probably in 4.2.10, but certainly in 4.2.12.

(When I updated to 4.2.12, I noted that I still had the Guest Additions for 4.2.8 installed, and likely (by mistake) when I retested this when asked 3 months ago it would have been fixed then if I had remembered to update the Guest Additions to 4.2.10 also.)

Host+F to enter full screen does not select the correct screen size when the monitor is rotated in portrait mode, I'll open a separate ticket. Please close this ticket (unless OP/user usdy says otherwise).
