Broken Sites after Brave update on Ubuntu Linux

I have several machines running on Ubuntu Linux 20.04.2 LTS and after each one updated to Brave Version 1.25.68 Chromium: 91.0.4472.77 (Official Build) (64-bit) in the last few days, several website pages are broken, including https://start.duckduckgo.com/ , https://bulb.co.uk/ , https://onlinebanking.nationwide.co.uk/ , https://mail.protonmail.com/login and BBC Weather for my village. The last one is interesting because if I access my local BBC weather page directly from a bookmark, the page is displayed incorrectly, but if I access by first selecting “weather” from the BBC home page and then selecting my location, the page is displayed correctly, despite the resulting page link shown in the search box being the same in both cases. The format of the display error is either a partial display of the page, or a brief correct display followed by whiteout.

I have reported all the web pages that break via the option in the Settings menu.
