Canvas rendered twice on android build

Works fine on android build with 2019.4.21f, or editor

Renders twice on android 2019.4.32.f, 2019.4.35.f, 2020.3.28f

3 draw calls right on top of previous 3 draw calls

I also noticed weird performance spikes.

Just found out that I had both a Canvas and a Canvas Renderer on the same GameObject. Removing the Canvas Renderer did the trick. However, I still don’t understand why the double rendering didn’t happen in the editor.
