Whelp, it's back to 1809 for me. I was having a problem with Intel (yay Intel) where it kept pesturing me to update the driver on the Intel HD Graphics 615. So after much effort, I finally got the driver updated to 26.blah.blah.blah. While it did resolve a weird screen flickering issue, touch scrolling in Firefox went to pure crap. Sure it's always been janky, but suddenly it was even worse before. No amount of uninstalling or adjust the settings worked. Eventually I decided to nuke the entire thing and start fresh by using a recovery drive. This time around I'm going to wait to get the update through Windows Update, and nope I haven't even installed Firefox yet. Running with Edge for now.
