Windows go half-maximized on wrong monitor

[Alistair Buxton]

Binary package hint: compiz

To reproduce:

1. Have a dual head system with nvidia/twinview.
2. Open a window on leftmost/primary monitor.
3. Drag window to right edge of rightmost/secondary monitor.

The window goes half-maximized on the left monitor instead of the right monitor. This doesn't happen when dragging to the top or left of the rightmost monitor. If you drag the half-maximized window directly over to the right edge again, it maximizes correctly. See attached video...

This happens with both classic and unity.

[Alistair Buxton (a-j-buxton)]

Update: this only seems to happen with gnome-terminal windows. I think it might be because gnome-terminal resizes in fixed increments.

[Kristijan Puljek (sampleofsoul)]

Happens occasionally, not sure if I could reproduce it willingly though.

[Alistair Buxton (a-j-buxton)]

This seems to be fixed in Oneiric

[Sébastien Pierre (sebastien-type-z)]

I can reproduce this consistently (as well as #976627) by either using Grid or clicking the maximize button on the window. The window is invariably maximized in the left-most screen, while the window was originally in the right-most screen.

[Daniel van Vugt (vanvugt)]

This could be the same root cause as bug 751605. Not sure yet.

[Jim Randall (jim-dreadfest)]

This happens to me a lot on Precise (with Unity-2D) when doing full maximizing. I do have different monitor resolutions.
If it helps, I've been able to work around it a few times by half-maximizing then maximizing after that.

[Daniel van Vugt (vanvugt)]

Can anyone still reproduce this in Ubuntu 12.10? I can't.

I can however reproduce bug 1068173, which might be related.

[Demortes (demortes)]

I still reproduce this bug. Just as stated above. All udpated.

[Eleni Maria Stea (hikiko)]

We didn't manage to reproduce this bug which is also quite old. Therefore I changed its status to Invalid. If you still experience this issue in one of the supported Ubuntu releases, please feel free to re-open it and update the description. Thank you!
