[Alex Boardman]

See attached video for behavior. When resizing a snapped window, it jumps to the other display.

[Launchpad Janitor (janitor)]

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

[David Overcash (funnylookinhat)]

Also affects nvidia proprietary xserver.

[Bilal Akhtar (bilalakhtar)]

I don't think the X server is to blame for this. Instead, Compiz is the most likely culprit here.

[Daniel van Vugt (vanvugt)]

I can't reproduce this bug with the latest compiz/unity. Can anyone else?

[Mathieu Comandon (strycore)]

Nope, it's still here.
It happens a lot when grabbing a (semi) maximized window with the Alt key and dragging it. Depending on where you grab the window or how fast you go, the window will "jump" to the viewport below.
If I recall correctly, it used to happen with fully maximized windows but I can currently only reproduce this with semi-maximized windows.

[Bilal Akhtar (bilalakhtar)]

This bug has been lying untouched for a while. @Mathieu - Does this still happen as of Precise w/ latest updates?

[dino99 (9d9)]

That version has reached EOL since a while, so it will not receive update. If that issue still exist, report again using ubuntu-bug.
