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.
