Contour lines after downloading from cloud

i have rdp into a shapespark server i host in my cloud. after downloading a scene from shapespark cloud, i see some contour lines

please tell how to fix this

somehow this issue is solved after reinstalling shapespark.

Typically glitches like that show up, when there is too much post processing applied, checking tone mapping & color mapping in the camera settings should be the first step if it happens again.
