Description of the issue: After installing Brave v1.87.192 (arm64) on macOS, I see visible margins/padding around the webpage area. The browser does not fill edge-to-edge even when the window is maximized or in full screen. The effect looks like a border around the content. There was a previous si…

@diddler Perplexity.ai suggests → Check Safari/Chrome on the same Mac, same display, same fullscreen/maximized mode. If that goes truly edge‑to‑edge, the issue is Brave’s current build on Tahoe, not Tahoe itself. Try Brave in normal “zoomed” window (green button once) versus true fullscreen (gre…

[image] diddler: there is a visible rounded margin/border on all sides Ahh, I think you have Rounded Corners enabled. Though, it shouldn’t be doing this in full screen. But go ahead and head to brave://settings/appearance and see if this is on. If it is, try disabling it. [image]

Yeah lets see if the rounded corners resolves the issue. @MasterLink is right though – shouldn’t be happening in full screen but still worth testing.

@diddler Maybe worth the effort to work that switch one way, then Exit / Quit the browser; followed by, start the brower and work the switch the other way; and repeat - maybe that will “jar things loose?”

@MasterLink thanks for testing. Looks like someone has opened and issue for this on GH as well – I’ve added a couple of the threads I’ve seen and let some folks know in channel internally: line appearing at the top of some full screen videos. …

Actually on second-look its not rounded, its just a normal square padding on the top, left and right edges of the video (plus rounded corners are already off anyway). The weird part is I cant even take a screenshot to show the black edges, as the cursor only allows me to go to the corner of the vid…

I also have the white line at the top of my screen. I’m guessing its not related since the white line issue is happening to a lot of people, but funny that it’s there too :laughing:

I too have this issue on macOS, mainly with non-YouTube streaming services. See photo.

YouTube has a less-severe version of the problem in that it puts thin grey lines around all four sides of the screen.
