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

[Sebastian Bachmann]

I can confirm this too.

I also noted, that it works for example for 2D images (like PNG) but not for 3D
data, for example VTK or MHD files.
Neither mesh edges nor 3D surfaces work in opacity mode.

I also downloaded the latest version (5.8) from kitware directly, which works
correctly for all files.

Best regards,
Sebastian
