When dragging maximized windows in expo mode, any side-snapped windows will follow

[psypher]

This issue occurs when any application window has been snapped in any position of the screen, in the background, and a fullscreen application is in the foreground. When going into Expo zoom-out mode, to see all 4 desktops, and you try and drag the fullscreen application to another desktop. The screen will perform a really ugly flicker screen corrupt, and drag any and all SNAPPED windows below the fullscreen app with it to the other desktop. You can clearly see this happening while the flicker takes place and the original desktop is left blank.

BUT if you were to instead double click the original, now blank, desktop to return to it, you will find the snapped windows are in fact left behind and the fullscreen app has been moved. BUT if you instead dbl click on the new desktop, where you have moved the fullscreen app to, you will find that the snapped apps did in fact move with it.

This happens when the window has been snapped using the mouse to drag or using the shortcut keys ctrl-alt-1/2/3/4/5/6/7/8/9. It occurs in both 64bit and 32bit versions. This also happens with any application, not just terminal.

I have tested this issue on my current main Dell XPS laptop, installed with 64bit 12.04 (nouveau driver) and this occurs in a Virtual machine running in virtualbox with software 3d rendering.

So the issue is not related to platform or graphics driver. It's easily reproduceable. Note this issue ONLY occurs with snapped windows, does not happen with windows that are not snapped.

Please see my atattached video of this issue in 32bit virtual machine

Any update to this, could someone please confirm this bug?

Thanks

Hi all,
beta 2 is out, this is still happening and this bug has not been assigned or confirmed yet, please could someone look at this. It's extremely annoying to have a properly ordered desktop, zoom out click on one screen and then have randomly apps jump to the screen you trying to go to.

Please help, this bug is falling through the cracks!

I have tested this with the nvidia and nouveau drivers and problem still persists. The flicker when moving apps and the issue where apps get snapped to other desktops when zoomed out and selecting an alternate desktop.

Problem also happens with and without multi monitor setups

Looking at the video I too can confirm a similar bug (I'm not using unity but instead gnome-panel with compiz enabled).

I can reproduce.

[jhfhlkjlj (fdsuufijjejejejej-deactivatedaccount)]

For me, I can only reproduce this with the control+alt+keypad corner cases, not the control+super+left/right cases.

I believe this is a duplicate of bug 882754 with different symptoms. Dragging a window to a different workspace in expo is technically a workspace switch (switch happens on ungrab to update the window position correctly). This particular issue has been fixed in compiz trunk. Thank you for reporting!
