To reproduce:
-
load a poly mesh, show it in a RenderView(view 1)
-
Filter-> Clip → Apply
-
Uncheck “Show Plane” in Properties Panel:
-
split current layout horizontal, Chose RenderView(view 2)
-
now if you try to change view position in view 1, plane will appear and Show Plane option no longer working.
-
To make Show Plane working again, your can delete clip filter and create a new one, but never try to active other view in same layout.
