Quick question, what have I done wrong, for some reason the texture is glitching.

[JEAPI-DEV]

So I tried having a cube that rotates according to the mpu6050 which data is read and send via a Arduino Uno. It works perfectly expect for the cube glitching in textures (I tried using different cubes/objects) but the same thing happened.

Also feel free to let me know if I could have done anything else better. Thanks in advance.

This is the main issue with the package. I've experience this with any type of shape that had thin "walls" to put it simply. If you make a full solid cube you might avoid it. But if you put a texture on top, it will still happen.

And the package seems to not be mantained anymore. I would recommend to use impeler in IOS and in android we just need to wait till they get it running.

If you find a fix please share.
