issue about full screen viewing the XD output

Hello everyone!

From time to time, I notice there are some strange issues when I view the XD url using desktop computer.

Let me show you some simple one.

I suppose using the plain colour background but you can see there is some unknown pattern when I view it in full screen.

I encountered some issue that the whole layout is messed up as well.

See if anyone of you got similar issue.

Thanks!
