VirtualBox Crashes When Screen Count Changes

Reported by: Zane U. Ji Owned by:
Component: GUI Version: VirtualBox-7.0.4
Keywords: QDesktopWidget screenNumber Cc:
Guest type: Windows Host type: Windows

Description

I have a laptop with an external monitor connected. Everytime when I close the lid of the laptop, the virtual machine that displayed on the laptop screen crashes.

Virtual machines displayed on the external monitor won't crash even when that monitor is disconnected. They will be moved to the laptop screen.

The last message in the log file is:

GUI: UIMachineLogic: Host-screen count changed

The crash dump says the exception address is:

Qt5GuiVBox!QScreen::virtualSiblings+0x8

Please check the dump file and windbg log for details.

Same here with VirtualBox 7.1.4 and nvidia graphics. I have it when I use my monitor switch to connect the external display to another laptop. Virtual box guest crashes immediately. Workaround: Minimize guest window before switching . Workaround2 (works most of the time): disable 3d support in guest - which is not nice and has other problems.
