Most websites are broken and look like this. This is Reddit
Can you share your Brave version, OS, and shields settings (Brave icon at URL bar), and other example site/s? This kind of info is needed for troubleshooting.
I reinstalled brave and cleaned cache and tried disabling all shields to test and still all was broken. I did fix it however, looks like it was an OS issue and not Brave. I installed some windows 10 Updates and rebooted my PC and its all good now. Weird because the other browsers on my PC was not affected.
