Created attachment 458793 [details] Video of the bug while it's happening. Not sure if I provided the correct version. User Agent provided by the console: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/101.0.4951.54 Safari/537.36 I'm only reporting this bug here because although this bug happened recently in Brave Browser, it also happened another couple times, a while ago, in Google Chrome, and all of them on this Mac. Occasionally, while using the Browser on a regular basis, its rendering just gets messed up. Suddenly, all text from all sites disappear, many elements lose their styles, images stop working, some elements get a green background. Even the browser's interface falls victim (tabs, bookmarks, inspector etc.). However, videos continue playing. I could not find how to replicate this bug, i didn't identify what triggers it, and it happens very rarely, but today, it decided to happen twice in less than a hour. It probably happened around 6 times in this Mac in a timespan of 4~5 years. In some occasions, the bug happens all of a sudden, and all at once. But sometimes, it happens as you interact with the browser (e.g.: the tabs are fine until I hover it with the cursor; an image is fine until you hover on it). Restarting the Browser fixes the problem. I've included a video capture of the bug.

Despite the UA string, Chrome (nor Brave) has used WebKit since 2013. You probably want the Chromium bug tracker: https://bugs.chromium.org/p/chromium/.
