Public bug reported:
When moving certain windows across displays, the system may suddenly
halt and has to be powered off
SYMPTOM
Either the window being dragged suddenly jumps to the top-left position of the
external display to the right (ie. display 2, the first external display) and
the system halts, or the system halts while the window is being dragged across
the internal display
Affected applications:
Virtual Machine Manager, Vuirtual Machine window
LibreOffice Writer
Other problem
If a Libre Office Writer window is opened on the internal display, ie by
launching LibreOffice Writer, the system halts.
IMPACT
Critical: in-app data loss, fsck data loss, forced system reboot
GETAROUND
Do not drag halting apps between displays
To move a LibreOffice Writer window, close it, and launch LibreOffice from a
terminal window on the destination display. On command libreoffice --writer,
LibreOffice opens on the display where
the terminal window is located.
For Virtual machines, close the window, move virtual machine manager to the
destination display and open the virtual machine window there.
The halt is similar to how the system halts when the kernel command line
parameter i915.enable_rc6=0 is missing.
