Issues with rectangle backgrounds on online links

[mtrichard-astek]

I have made some screens with Adobe XD, along with a prototype. 

On the local machine, everything works fine. 

I then create a link so that I can share it online. 

But I face an issue on the link, one of the rectangles (the one that represents the sidebar) has no background and thus, messes up my design. 

Here is the part of the design under adobe XD : 

And here is the result under the link : 

As you can see, the background is all "snowy" and see-through. 
I tried to delete the incriminating rectangle to recreate it, to no effect. I tried changing the background, the shadow, the border ... To no effect. 

I'm pretty new to XD so I do not know what is happening, could someone explain to me how to resolve that ? 

Thank you in advance.

Hi, does this problem only occur with this file or even with others?

Hello, this is the second time it happened on two different files. I'm not able to reproduce it on demand, although generating new files usually resolves this (that's what I'm doing when I face it, but I would like not to face it though !)

I have managed to find part of the reproduction process, the issue only happens when using the full-screen option. Nothing happens when the prototype isn't in full screen mode. For information, I'm on Chrome 77.0.3865.90 (Win10), in case it might help.
