Me too. It has been noticably worse the last two months, and I often see things that look like CSS loading errors. I'm using Firefox (beta) and uBlock Origin too, so that could be a common factor. But it varies from load to load. Sometimes it's completely fine. So I don't think it's likely to be a simple rendering bug. I've been using Firefox and uBlock Origin for years, and LinkedIn more over the last year. I only noticed rendering problems in the last couple of months. (Plenty of other bugs. Search is unreliable, and the mobile app is not without bugs either (some buttons don't do what they're supposed to), but rendering seems ok on mobile.)
