[Luke Hoersten]

Maximizing a window on the secondary monitor with Nvidia twinview erroneously moves the window to the primary monitor to maximize it.

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

[Luke Hoersten (lukehoersten)]

It actually looks like this just happens with Google Chrome browser for me.

[stianst (stianst)]

This happens to me with any application when maximizing. It also happens when using ctrl+super+up/down/left/right and when using ctrl+alt+num. It doesn't happen all the time though, sometimes the window is resized on the secondary monitor as expected, while other times its moved to the primary monitor. I haven't been able to detect any particular pattern for when the application is moved to the primary monitory and when it stays put.

[Luke Hoersten (lukehoersten)]

Yeah actually same here. I thought it was just Chrome but it seems to be intermittent on all apps.

[Joe Alam (yothsoggoth)]

I installed Compiz and CompizConfig Settings Manager (CCSM) and disabled "Snapping Windows" in that (to enable Wobbly Windows), which seems to have fixed this issue for me.

[Luke Hoersten (lukehoersten)]

I've pinpointed the problem to when the window being maximized spans both monitors it becomes maximized on the first monitor even though I dragged and snapped the window to the top of the second monitor in order to maximize it.
