This seems to be an effect for some users after they update to the new version. The workaround mentioned by @fictive of disabling that windows setting is in the link below. And, as has been pointed out, changing that affects all the system windows although it does allow you to read tab text in Brave. I don’t think anyone knows exact steps to recreate this issue (yet).
Edit: Updated Google Chrome and I do not have an issue there either. Has anyone with the issue updated Chrome and does the issue occur there also?
