Merge Blocks filter creates incorrect output
If data that was created in Paraview 5.5.2 is loaded into Paraview 5.6.0, and the Merge Blocks filter is used, the results look incorrect. This seems to happen to point data. The cell data still looks correct.
If I load the data in Paraview 5.5.2 and use Merge Blocks, it looks right. Using the latest git master of Paraview also looks right.
I have included a screeenshot of what this looks like, and have attached the data used.
To reproduce, load the data in Paraview 5.6.0, and apply the Merge Blocks filter, and have it show point_density.
