We are researching the Moodle platform for our students to use. We have a high percentage of our students without home internet access, so we are looking at the mobile app and also the Moodle Desktop app to provide offline functionality for them. It is working great with the mobile app, and the desktop app works great on a Mac. Our linux laptops (which will be the majority) aren't working correctly after just a few minutes. The app launches and things appear to be working fine, but then the app will turn solid white, and will remain that way indefinitely. I've left it on this screen overnight, and no change has happened.
I've not been able to see this mentioned anywhere, so I thought it might be an issue with the image we are using for our linux deployments. I've downloaded a fresh version of a vanilla Ubuntu ISO, and the same issue happens right after an install. Is there a component I'm missing that would be causing this problem?
