Local Rendering not working on paraview >= 5.13

[UlysseDurand]

The following examples show no rendering when using local rendering with paraview:

• https://github.com/Kitware/trame/blob/master/examples/07_paraview/SimpleCone/LocalRendering.py
• https://github.com/Kitware/trame/blob/master/examples/07_paraview/SurfacePicker/app.py
• https://github.com/Kitware/trame/blob/master/examples/07_paraview/TimeAnimation/app.py

Other paraview examples render fine.
These three examples have paraview.VtkLocalView in common (or VtkRemoteLocalView and renders nothing when switching to local rendering).

I am using Ubuntu 24.04.4 LTS

.venv was created with the following commands

python3.10 -m venv .venv
source .venv/bin/activate
pip install trame trame-vtk trame-vuetify

I ran the examples with the following command
~/Downloads/ParaView-5.13.0-MPI-Linux-Python3.10-x86_64/bin/pvpython examples/07_paraview/SimpleCone/LocalRendering.py --venv .venv

It stopped working after 5.12.1.
I tried with different versions of ParaView, 6.1 and 5.13.0 don't work but 5.12.1 works fine.

Also, I would like to notice that, using the SimpleCone example, if I try to load a file with simple.OpenDataFile(path) if path is a path to a .vtp, the rendering does not work, if path is a path to a .vtm file, it works well.
I am using Paraview 6.0.1 with a python 3.12.

would that mean the rendering works for composite datasets but not for regular datasets?

It is probably related to the changes done recently on actor/mapper serialization.

IMO, it looks like something like that yes

Paraview 5.13.0 is 2 years old though.

we tried with @UlysseDurand and it was still not working with an older trame-vtk AND a recent ParaView. So I'm really confused.

hum that is strange...
