Strange visualizer window in Vapor3.4

I just installed Vapor 3.4 on MacOS Big Sur. When I open Vapor, the visualizer window is transparent. After importing a WRF-ARW file, a black visualizer window with only 1/4 size appears on the lower-left corner. Any fix?

The transparent window is a know problem on the Mac, but the 1/4 size window should not happen. Can you possibly share a smallish version of your data?

Here is one wrf data file I am using:

Thanks.
