All,

when switching virtual desktops, windows from desktop 1 appear on 2 and
the other way round.

17:00.0 VGA compatible controller [0300]: NVIDIA Corporation GK208
[GeForce GT 710B] [10de:128b] (rev a1) Subsystem: Micro-Star
International Co., Ltd. [MSI] GK208B [GeForce GT 710] [1462:8c93]
Kernel driver in use: nouveau Kernel modules: nvidiafb, nouveau

Is there any workaround? It is very annoying!
