Thanks a lot for your feedback. I would need to know what kind of device / operating system and browser that is!

The device is a Samsung galaxy note 10, software version N970USQS7FUH7, and the browser is chrome! Also I deeply apologize for my belated reply!

The issue looks like some browser or hardware acceleration issue. Does it work when you try a different browser on that system (for example firefox)?

using a different browser fixes the issue thank you
