pyvista trame wasm example draws vtk window in addition to browser

[jtristano]

I'm much more comfortable with pyvista than raw vtk python so I want to create a web app using pyvista and trame instead of trame, pyvista, and paraview. I've tried this example

pyvista-tutorial/tutorial/06_vtk/d_wasm.py

Line 2 in 759f7f0

VTK + WASM

However, it draws a vtk window as well as the browser window. How do I eliminate the vtk window and keep my wasm?

btw, I'm running this on wsl

found the problem, offscreenrender wasnt enabled
