I have seen some other reports like this. There is some anecdotal reporting that it might be caused by a bad interaction with streaming software. Beyond that, the best recourse is to go through the checklist below, and if that doesn't isolate a cause, send the console log from Step 4 in a Help Center Request Could you please carefully work through these steps of our guide to Solving Technical Issues ? Step 1: Make sure to use the right browser Please check if these issues persist when using both Chrome and Firefox. Step 2: Ensure that there are no extensions/addons interfering with Roll20 Please disable all add-ons/extensions. Step 3: Clear your cache If none of the above succeeds, please thoroughly work through Step 4 . (Don't forget the complete Console Log!) Thank you!
