Maximized windows do not scale correctly with Unity and TwinView

[Ramón Rocha]

Binary package hint: unity

Normally, a maximized window on TwinView just maximizes on one monitor. On Natty, with two monitors and nvidia TwinView, a maximized window will cover one entire monitor and part of the second monitor or sometimes part of the window will be off the screen depending on the layout of the monitors This is confusing.

can you give more information about your configuration? i use twin view and maximization works as expected.

[Ramón Rocha (ramon.rocha)]

I'm not sure what other info I can add besides what's included in the attached log files. The left monitor is 1280 x 1024 and the right monitor is 1920 x 1080. If there is something specific needed then I can provide it.

When I attempted to maximize on the left monitor, a portion of the window overlapped onto the right monitor. See previously attached screenshot.

I will try to reproduce the issue when the tracker at xorg.qa.ubuntu.com resets for week 4 testing.

[BLewis (lewishnl-gmail)]

I can confirm this.

I had this bug, I then enabled the separate X screen option in the nvidia control panel and it fucked up afterwards. I backed up from the previous config of twinview and it worked fine with dual fullscreen as expected. I know also have two logout parts of the bars too as a consequence. I can only assume it was solved by an update I did while it was last on, or by simply the reboot anyway.

Thanks for looking into this BLewis. The xorg qa community team was seemingly forgotten about as nobody ever reset the tracker for week4.
