Hi Mattia, you are probably referring to the K3D jupyter backend of vtkplotter. This not at all controlled by vtkplotter. You can check its functionalities [here](https://github.com/K3D-tools/K3D-jupyter). M.

@panangam you can do it this way: ```python from vtkplotter import embedWindow embedWindw(False) ``` it is a bit strange though that it take so long..

that's interesting.. on my system it only takes 0.7s to show it:  same if i use `vtkplotter.embedWindow('itk')` How much does it take outside jupyter e.i. a normal python script?

Uhmm, I would maybe check some of the k3d standard examples to see if the problem is still there. https://github.com/K3D-tools/K3D-jupyter/tree/master/examples

that sounds weird indeed because if show() returns in 0.7 sec i cannot think of anything that would slow down the execution afterwards. I reopen the issue in case of...

Hi @panangam I think I found the problem in the way vertices receive their color individually. Please try `pip install vtkpotter -U`  Now the color is...

> This worked perfectly for me, thank you! I'm still surprised your machine could actually still run the scene smoothly with all the vertex colors. To clarify, did vtkplotter use...

Cool... Thank for this useful feedback! I tried increasing the nr of triangles with `res=100` and dont see any problems on my system, up to 1M triangles is still ok...

I think you are using latest version of k3d whereas i'm using an older one.. not sure if this can explain the initial problem.. I'll leave the issue open in...

thanks! unfortunately this seems a limitation from K3D (see https://github.com/K3D-tools/K3D-jupyter/issues/178 ) so i'm not sure when they would be able to fix it..
