Maybe related to #16942 (closed), but only happens in client-server mode when remote rendering is enabled.

ParaView at v5.1.2-553-g3c63add and VTK at v7.0.0.rc1-2553-gbab11e0.

1. Start ParaView, connect to a 2 rank pvserver.
2. Create Sphere, Apply
3. Now resize the window. The rendering disappears.
