Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem?
Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.9 kernel[0]. If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. Once testing of the upstream kernel is complete, please mark this bug as "Confirmed". Thanks in advance.

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.
