White bold border appears in full-screen mode on Brave browser

Description:
While using Monkeytype on Brave browser, I am getting a white, bold rectangular border around the screen whenever I enter full-screen mode.
This border is visible throughout the entire typing test and is very distracting.

Steps to Reproduce:

1. Open Monkeytype.com in Brave.

2. Start any typing test.

3. Enter full-screen mode.

4. A bright white border appears around the whole screen.

Expected Behavior:
Full-screen mode should display normally, without any border.

Actual Behavior:
A thick white outline appears only on Brave.

Tested Browsers:

• Brave → Bug occurs

• Chrome → No issue

• Edge → No issue

• DuckDuckGo Browser → No issue

Same on Ubuntu 25.10 Mate. Brave 1.85.111.

Seems that the white border is around the window regardless of the full screen or any other mode. What is, for me, even more super annoying that the scrollbar on the right is inside the border, and scrollbar is not on the extreme right when window is maximized. Breaks Fitt’s law. If you use scrollbars to scroll a maximized windows, this make the whole browser unusable. I cannot use this before this is fixed.

Checked: NO similar problem on Windows 10 22H2 19045.6575. Same Brave version.

Hey OP, my problem on linux was solved on this other thread. Perhaps works with you too?

Visible borders around webpages in full-screen after latest Brave update on macOS

Description of the issue: After updating Brave to version 1.85.111 (Official Build) (arm64) on macOS, I now see visible margins/padding around the webpage area. The browser no longer fills edge-to-edge even when the window is maximized or in full screen. The effect looks like a border around the content. The issue is visible on all sites, but it is much easier to see on dark pages. On bright webpages the margins are still there, but harder to notice. How can this issue be reproduced? Open …

Yep, looking closely it appears for some reason rounded corners is being applied in full screen. On Windows they don’t show up on MonkeyType when in full screen, so perhaps the bug is rounded corners is showing up in full screen at all on Linux (Rounded corners should never be visible within full screen for obvious reasons such as this).

Can you confirm if you enter full screen via F11 on any site that the border is still visible? (And, if disabling rounded corners it goes away?)

Yes. It’s showing in most of the websites
I found one more thing: it (border) changes color when I change the Windows theme.

I tried uninstalling and reinstalling Brave, and I also changed several settings, but this issue still isn’t fixed.
