UNKNOWN ROOT WINDOW TYPE DETECTED (Tilda), please file a bug

I think i can do a hack. like first run nitrogen . then run tilda .nitrogen will crush but walpeper will be not removed. (bad hack)

another thing is if i run nitrogen (GUI) .. there is no 2nd monitor option. if i kill tilda "pkill tilda" it will work as it should be work.

~~thanks for reading
