Problems watching in Plex Web App



sometimes I've watched movies or series on my pc (windows 10) using Plex Web App and I have not any problem antill now.
If I play anything form my media library in wide screen, the images present some annoying effects like black and white lines around the shapes. If onstead I watch the video without entering the wide screen mode I've not any problems.

Could resolve this by changing any setting or it's a software bug?


Can you provide a sample file that does this. What browser are you using?


I'm using Chrome. The problem is that all the file suffer of this problem. I've tried to stop the video so i could attach an image but if i stop the problems vanishes.


I've tried using Microsoft Edge and till now i've not found any problems. Could it be a problem related with Chrome?
