Coloring issue surface representation element-wise field Paraview 6.0 with opacity < 1.0

ParaView Support
1

For the attached VTK dataset, when I color it by partition and I use representation Surface, it is colored correctly when opacity == 1.0 but incorrectly when opacity < 1.0, see attached figures. If I use another representation (Surface with edges) or plot a nodal-wise field, it is colored correctly. I can also replicate the issue in Paraview 5.13.2, 5.12.0 and 5.11.0. If I plot another element-wise field, I obtain the exact same wrong coloring when opacity < 1.0. I can also replicate the issue with a vtx version of the same dataset.

opacity = 1.0
opacity = 1.0854×401 14.3 KB

opacity = 0.5
opacity = 0.5908×413 22.3 KB

It looks like there is a lot of overlapping between the different datasets:

This is probably causing that effect.

Sorry, I attached the wrong data @mwestphal . I attached the data for the first processor at different time-steps. Here is the data for all the processors at the first time-step.You should be able to open it from the pvtu.

Looks fine with opacity using ParaView 6.0

Do you have Depth peeling on? Turning it off seems to fix the issue for me. (Settings > Render view > Translucent rendering options > depth peeling)

I do not.
