[Bug 771632] Re: The strange 1px width windows appears after several days of working


Interestingly I've found the same 1px windows when working on Xmir
recently (no compiz/unity involved). Although on the Xorg server side
they are usually flagged as invisible so are not meant to be displayed.

  After several days of working (with xorg modes switching, suspend-resume cycles) strange window appears in the screen. The window has shadows, but no buttons. The window can be activated, than context menu available (alt+space). Window can be resized and moved. Window has no icon on unity dock or in compiz switch window dialog. If resized - window border appears with buttons and black background. If i close window - unity closes to and restarts after several seconds and without that window.
