Switching workspaces causes graphic issues

[Erik S]

This problem occurs since my update from Ubuntu 11.10 to 12.04 with Unity 5.12 and Compiz 0.9.7.8:

When I switch through my workspaces (6 workspaces: 2 rows with 3 destops) I can see for some milliseconds a window which is neither on the workspace switching from nor on the workspace switching to. But in the same row, when I switch horizontally.

Example:
Row 1:
Workspace 1: firefox
Workspace 2: //nothing
Workspace 3: thunderbird

Row 2:
Workspace 4: //nothing
Workspace 5: skype + empathy
Workspace 5: banshee

And now: When I switch from 1 to 2 I can see parts of the Thunderbird window but just for a very very short time. Thunderbird even appears on the 2. Workspace on the switcher preview (Desktop Wall plugin in Compiz) for a short moment...
Same for 2 -> 3; 4 -> 5; 5 -> 6 and the other way around. But not when I switch to another row (e.g: 1 -> 4)

I took some interesting screenshots. It seems like all windows switch to their left workspace for a millisecond... (see screenshot 2)
The windows and workspaces on the screenshots are equal to ones noted above.
