Been using Beta for a while with no issues, but now there are suddenly borders on each side of the screen.
It’s only on Brave Beta, don’t have this issue on other browsers, not even on normal Brave.
Zoom in to see better, have pointed with arrows also.
Same here, very distracting.
same here its frustating man 
Hmm I’m not seeing these borders on my end. What version of Windows is everyone here running? Can you also confirm that it’s happening on all websites?
Apologies — I do see it now. Wasn’t even clear we added it — you can disable it by going to brave://flags and setting the #brave-web-view-rounded-corners to Disabled. I will also pass on the feedback that is given here.
It fixed it
thank you very much
Edge and Arc browsers have the same kind of border. It’s trending. I’m not going to say I don’t like it.
Thank You So Much Sir For Giving The Fix 
hopefully this flag dont get removed when chromium team removed something similar in flags which is similar to this flag…
Also, consider adding this as setting in appearances in the next update… thanks
Gladly there’s a flag to remove this… Weird that it’s enabled even when there’s no sidebar, and vertical tabs are not enabled
Thanks for the flag! It removed the additional border successfully.
