I also have this issue with my Lenovo Laptop (Intel Haswell-ULT Integrated Graphic, LCD Panel set to OFF) with ViewSonic external display(4K, external, Only monitor).
The external display is shared with a desktop, every time I switch the input of the monitor back from PC to laptop, or when the laptop come back from power saving, some windows go out of screen and there has no way to bring them back to view except make them maximized. -- You received this bug notification because you are a member of compiz packagers, which is subscribed to compiz in Ubuntu. https://bugs.launchpad.net/bugs/919437 Title: Lost window, cannot get it back.
