This issue has been ongoing for several months on my Windows 10 PC using the latest version of Chrome. When loading a website, it occasionally loads in "simple" mode (I'm not sure what the proper term is) where there is very little formatting. Sometimes pages might return a "you need to upgrade your web browser" message. When the page loads like this, I hit F5 and then it will usually load normally. Occasionally I might need to hit F5 multiple times before the site loads properly, but it will eventually load. The strange part is that the issue occurs sporadically. I might go a week without any issues at all, then one morning I will have problems loading several webpages, then it will return to normal again.
I have tried all the usual browser troubleshooting steps (clearing cache, cookies, etc.), but that hasn't helped. At this point, the sporadic nature of the problem leads me to think it might not be related to the browser at all. I haven't ever seen the issue in Edge, but I don't use Edge very often so I can't confidently say that it doesn't occur in Edge. Has anyone ever seen this before? What could be happening to cause this type of behavior? An example screenshot of what happens when I load webpages is attached. You can see there is very little formatting and it is mostly just text and links.
