Lag when scrolling [scrollrect + vertical layout group]

You can download the project here: https://gitlab.com/javioverflow_public/scrollrect_lagging_on_android/tree/master

When I install it on my android device (2gb, 16gb, good graphic cards... I can run 3d games smoothly and my project is just a canvas based app) and I scroll the list, it lags a lot. If I execute it on the unity editor, it doesn't lag at all.

I don't know what to do... It's really weird that so few components lags that much and I don't know where to look for.

Thanks in advance!
