Windows Rearrange and Resize without User Interactions

[bob]

!What I expected to happen

Windows stay in the same place with the same dimensions

!What happenes (happens) instead

Open windows will be re-arranged. Some will be resized, others maximized and some hidden. If workspaces are enabled, some windows will be moved to a different workspace.

Some of the ways to reproduce this:
* with workspaces enabled, merely switching workspaces (often but not always)
* with or without workspaces enabled, if the machine goes to sleep/suspend

$ lsb_release -rd
Description: Ubuntu 16.04.1 LTS
Release: 16.04

Problem reproduced on multiple machines less than a year old:
* System76 Lemur with external Dell monitor +
* 2016 HP Spectre x360 with a standard install of Ubuntu) with no external display

Frequency: very (essentially any time I'm away from a machine for more than about ten minutes).

!Attempted Solutions

* Disable all hot corners/edges, etc. on both machines
* turned off the Lemur's internal display (the psuedo disable in System Settings > Display).
* turned off workspaces on Lemur

The only noticable difference was that it reduced the places I had to hunt for the windows I need to move and resize to begin work again.

e.g. put my Development environment back in working order.

We are sorry that we do not always have the capacity to review all reported bugs in a timely manner. You reported this bug some time ago and there have been many changes in Ubuntu since that time.

Ubuntu 16.04 (xenial) reached end-of-life on April 29, 2021.

Do you still see a problem related to the one that you reported when using a currently supported version of Ubuntu? Please let us know if you do otherwise this report can be left to expire in approximately 60 days time.

Thank you for helping make Ubuntu better.
