I tried the tip from Anthony Statera - thanks. This did not work for me. I tried a clip before rebooting and after both the same. The really strange thing is that the first part of the clipping is reasonable, as I scroll down the clipping the text is fuzzy. I have 3 monitors, 1 4k and 2 1920 X 1080. Been running the 3 monitors for a couple of years at least. No problems until recently. My work around, although not ideal, us to use my Samsung TAB S2 running Android 7. The EN clipper is still producing clear text.
