Hi, @amura11 - thanks for submitting this issue! Hmm this is really strange, and I'm seeing the same behavior on 5.0 too.
@jsuarezruiz do you know what might be going on here? Here's a repro: Issue13315.zip

P.S. You did a great job filling out the fields!! The only thing I would suggest for the future is that you share as much code as you are able - in this case, it would've been helpful to see the full <Path> code you added. A "repro" project - aka your project or a sample project reproducing the issue - in the form of a zipfile / GitHub repo upload is also always super helpful!

In case this helps, I came across a couple more Paths that render strangely on iOS. Again both were taken from MaterialDesignIcons.

Is there anyway to get this into the next build? I was hoping to use this in my application but until it's fixed I'm going to have to go back to using images which is less than ideal

Any progress on this? Is there an estimated release date? Thanks in advance.
