I hope this is the correct forum for this. If FX or 3D dice have stopped working for you, and you use Chrome, check <a href="https://get.webgl.org/" rel="nofollow">https://get.webgl.org/</a> (as Roll20's settings page suggests). If you don't get the spinning cube then try the below workaround. Credit to dubbekarl (reference to a bug report that gives details here): <a href="https://productforums.google.com/forum/#!topic/chrome/XIy6dtJY4uo" rel="nofollow">https://productforums.google.com/forum/#!topic/chrome/XIy6dtJY4uo</a> I first realized the issue with Chrome 54.0.2840.59 and still exists with the latest, 54.0.2840.87. Workaround in Windows (until it's fixed) Load Chrome with the following parameter: --disable_chromium_framebuffer_multisample An example if you want to edit the shortcut properties, you may want the Target filed to lool like this: "C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --disable_chromium_framebuffer_multisample Note : Not sure if it's relevant but dubbekarl and I both use an NVidia GTX260.
