When I get some time I am going to roll back the Firefox update and see if that is the actual cause of the issue. CTO of Roll20 here, and I would be very interested to hear if this issue is fixed if you roll back to a previous version of Firefox! Hi Mike T. I have tried rolling back to earlier versions of Firefox but situation persists. I am having no problems with Chrome, Edge, Brave or Norton Secure Browser. I am wondering whether or not it may be a graphics driver issue. I am actually getting a branch new laptop this coming week so will park this until then. Cheers B
