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.
EDIT: Removed incorrect data

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.
