Volume Rendering + Looking Glass Plugin Has Performance bug on Windows

I have just installed the October 3 Paraview nightly. The Paraview Looking Glass plugin integration works on surface and point data.

I can also volume render without issue, but when I volume render with "Render Active View On Looking Glass", it takes an exceedingly long time (~20 minutes, when the regular volume render takes ~10 seconds).

The data is from a 44MB text .vtk file , 3D rectilinear grid, float data, one fields.

The Windows box has an NVIDIA GeForce RTX 2080 Ti.

I can share the data to reproduce with the assignee, but not "fully publicly" as part of the ticket.
