@korina Hi Korina, tried it with another installation of a Firefox Nightly and you're right, it works as expected. I had a look @ my about:config, and I think I found the problem:
privacy.resistFingerprinting.autoDeclineNoUserInputCanvasPrompts was set to true to avoid tracking/fingerprinting of my browser. This seems to be a needed function for the correct display of the layers in Windy. When I set it to "false" and restart my browser, everything works fine. Anyways, this is a popular feature for security-minded people and there are also canvas-blocking addons installed by many people. Maybe you can pass that on to your developers so they can see if there is way to fix that? Thank you.
