advancedDynamicTextureMaterial keeps dangling even when the component is unmounted

[jinincarnate]

Hi I have created a 3d UI in VR using a similar code as shown in the link below

https://brianzinn.github.io/react-babylonjs/examples/gui/2d-gui

but when the component is unmounted all objects like plane, advancedDynamicTexture, and all other ui components gets destroyed, but advancedDynamicTextureMaterial (that gets created automatically) doesn't get disposed and keeps hanging in the scene. Is there a way to get its reference so that it can be disposed.

do you know the imperative solution? if you can make a regular babylon PG then I'm sure we can figure it out.

Hi i have tried adding babylonjs inspector to your example so that the issue can be seen easily. the code might run a lil slow just tried to cook up something fast.

Try it on https://codesandbox.io/s/relaxed-solomon-75zjci

as u can see in the image multiple instances of advanced dynamic texture material are getting created as we open and close the 3d UI

thanks @jinincarnate - I found the memory leak. the sandbox was a great repo.

@jinincarnate can you confirm it's fixed in 3.1.17?
