Issue with StoryMaps on a Raspberry Pi

AndrewRitchie

This might be an odd use case.

I'm trying to load a StoryMap onto an office display screen (TV on the wall), powered by a raspberry pi.

The pi opens chromium browser on boot, and loads 3 pages into tabs, and then cycles through the tabs every 15 seconds.

When loading a StoryMap, chromium (and tested with firefox-esr) will only load the placeholder image for the cover page, and will not download the fully rendered image. 

Using Chrome dev tools on my desktop, seems to show that the image should load in two parts:

However, on the pi, the blob doesn't appear to be triggered - I can't see any errors.

Is there any reason why StoryMaps wouldn't be working on a pi - are there any extensions I might need to enable? 

 

Cheers

Rtfm: I expect i may need to enable webGL support. 🤞

Solution: In the end I had to make sure Chromium browser was up to date, and enable OpenGL per: https://raspberrypi.stackexchange.com/questions/83113/webgl-does-not-work-properly-on-raspberry-pi-chromium-browser

1. use raspi-config to enable OpenGL (Full KMS)

2. remove "--disable-gpu-compositing'' from /etc/chromium-browser/customizations/00-rpi-var
