I have a little but still unconfortable problem when I watch a picture in Facebook and I switch it to fullscreen. (Not Opera"s full screen mode with F11, but Facebook's fullscreen mode with this little arrow in the pictures upper right corner.
In this case unlike other browsers (like Edge or FF) the fullscreen pictures is not fit to my screen. It's pops up 100% zoomed therefore I can see just the little piece of the picture. Yes, I could zoom out it with a lot of clicks but it" very slow and uncomfortable and I can't step to next picture only if I step back from Facebooks full screen view.
But in this case I have to change full screen again, zoom out to see the whole picture without comments (this is the matter why is switch to facebook's full screen mode -not Opera's full screen mode!!!).

Could you recommend me any solution or just like an extension to solve this problem?
I use the latest version of Opera, OS Win10.

Thanks!
