Bug#954329: paraview: opacity incorrectly handled by the debian bullseye(testing) package paraview-5.7

[Pierre Saramito]

Package: paraview 
Version: 5.7.0-4+b2 
Severity: normal 

Dear Maintainer, 

The opacity is not handled correctly by paraview-5.7 binary, 
as packaged on bullseye(testing) distrib. 
Here is a unix command that reproduces the bug: 

paraview --script=paraview-opacity-bug.py 

where the paraview-opacity-bug.py python script coulbe be downloaded at 

https://www-ljk.imag.fr/membres/Pierre.Saramito/tmp/paraview-opacity-bug.py 

This problem is specific to the debian package: the upstream paraview-5.7 
version is problem-free when I use the raw binary distributed by kitware: 

https://www.paraview.org/download/ 
https://www.paraview.org/paraview-downloads/download.php?submit=Download&version=v5.7&type=binary&os=Linux&downloadFile=ParaView-5.7.0-osmesa-MPI-Linux-Python3.7-64bit.tar.gz 

This opacity problem could perhaps be due to the mesa/opengl library, 
as packaged by debian bullseye(testing) ? 

Best whishes, 

Pierre
