SUMMARY

I use my laptop either with the internal screen, or with an external screen and the internal one disabled.
When I switch from internal to external, windows regularly end up on the disabled screen and thus outside the visible area.


STEPS TO REPRODUCE

I am not entirely sure how to reproduce this, but I usually do something like this:

1. Work with the laptop on the internal screen only.
2. Suspend the laptop.
3. Connect an external screen.
4. Resume the laptop. It is already configured to switch to the external screen and disable the internal one.

OBSERVED RESULT
Some windows end up outside the visible area. When I activate them from the panel, the animation indicates they are to the right of the external screen. This is where I used to place my internal screen before I decided to disable it instead.

EXPECTED RESULT
Windows should always be forced into the visible area.

In fact I don't quite understand why they are moved out to begin with -- something seems to move them all the way to the right. Maybe this is related to how I used to set up my external screen, where the internal screen was enabled and placed to the right of the external one, and the external one was primary. This is pure speculation though. Obviously since the internal screen is disabled, where it used to be placed when it was enabled should not have any effect,
