Windows often maximized to wrong screen in dualhead configuration

[Felix Möller]

Moving a window to the top of a screen creates the orange shadow as expected however the window goes to the other screen.

Will attach a video shortly.

This happens with firefox but does not happen with nautilus for example.

[Felix Möller (felix-derklecks)]

I would think Firefox is a part of the problem because it does not happen with other applications. Can anybody reproduce at all? It might just be triggered of replugging the external monitor ...

[Daniel van Vugt (vanvugt)]

Thank you for taking the time to report this bug and helping to make Ubuntu better. This particular bug has already been reported and is a duplicate of bug 751605, so it is being marked as such. Please look at the other bug report to see if there is any missing information that you can provide, or to see if there is a workaround for the bug. Additionally, any further discussion regarding the bug should occur in the other report. Feel free to continue to report any other bugs you may find.

Status changed to 'Confirmed' because the bug affects multiple users.

[Alexander Kops (alexkops)]

I can confirm that this bug occurs to me since yesterday. It only affects Firefox, all other Applications behave as intended. So I'm not sure that it's really a duplicate of bug 751605.
