Hi, I had a windows update a few weeks ago (Windows 10.1) and since then, the display in my Firefox browser is glitchy. I've included a screenshot, to show the glitch across the tabs etc, but it can also load pages of text with lines through them, so you can't read anything. Usually when you mouse over the glitchy bits, it'll disappear and go back to normal, but where there's no links (or clickable area, such as the right side of the bookmarks toolbar where I've got no bookmarks), it doesn't change. It seems to fix itself if I close Firefox and restart the session. Firefox is up to date, my computer is only a few months old, and this glitch doesn't seem to happen in anything else, so is this something I can fix? Thanks for any help! =)
