@HotCakeX Thanx for your feedback! This has been fixed recently and should be available in the upcoming Windows Insider Fast builds. Please let us know if you still see this issue after trying it on the next insider build.
Thanks that's good to know. so it actually has something to do with Windows and not the browser itself. black bars still present in build 18970 though (yesterday's release), i think fixes will be shipped in the next one.
Hi @HotCakeX, I am running Windows version 1903 (Build 18965.1005) and I can attest that I do not have any extra pixel around the browser window when running under Application Guard. Thank you @Arunesh for pointing this out! Thanks - Elliot
