Piston application panics on Raspberry Pi


#1

I have built a small application with Piston to show a slideshow of photos from my Flickr photostream:

The goal is to have it run on a SBC like a Raspberry Pi. It runs fine on desktop Linux machines but when running on an actual Raspberry Pi 3 it panics somewhere in gfx_graphics::back_end::Gfx2d<R>>::new. The error is not especially helpful as even a debug build lacks a line number for where the error occurs and there’s a number of unwraps in Gfx2d::new.

I was wondering if the error made more sense to anyone else or if anyone had any experience or tips running Piston projects on a Raspberry Pi.
