trace of multiview screenshots is bad
Traces/ Scripts of multiple view screenshots are bad. This has degraded since 5.6.0.
- Master (v5.6.0-1312-g8ce81b84), local server, Linux.
- Tools/ Start Trace. Just to make sure, Fully Trace Supplemental Proxies.
- Open can.exo. Apply.
- Split Horizontal/ Split Vertical/ Split the other (long) view Vertical. We now have a 2x2 of views.
- Highlighting each of the gray views, turn visibility on, showing the can in each.
- Not necessary - I clicked on +X, +Y and +Z in different views. Lower right view was just freehand.
- File/ Save Screenshot. BE SURE to save all views.
- Tools/ Stop Trace. Save this somewhere. Close the trace.
- Reset Session.
- Delete the saved screenshot.
- View/ Python View/ Run Script. Um ... Run your script.
All 4 views don't have correct images in them! (Note that the views are now possibly out of order, depending on the order you did "Highlighting...". I will write this up as another bug.)
I also received this set of errors/ warnings:
ERROR: In / snip /ParaViewCore/ServerManager/Rendering/vtkSMViewLayoutProxy.cxx, line 596 vtkSMViewLayoutProxy (0x4a5f440): Cell is not empty.

This is a showstopper bug for the 5.7.0 release.
