i am using Firefox and I have the issue that when I toggle the dice on, it automatically toggles off.  I am a DM and this is really annoying that the only person in my game group that cannot use the system is the DM!

I got my dice to work in Google Chrome, be warned I can't guarantee it works for you, or won't mess something else up.

In your browser go to this address:

chrome://flags/

 Find 

#enable-vulkan

 Set it to Enabled and relaunch Chrome.

This got my dice working in Chrome on Linux (EndevourOS).
