I teach and I've been happily using Bandicam for a couple of years to make supplemental videos for my students. Suddenly, Bandicam's videos are fuzzy. I teach and I usually use the screen capture (with myself in the lower corner). I am fuzzy in the camera, and also the stuff on the screen is fuzzy, so it's not just one or the other. I'm using a Samsung laptop and Windows 10. Nothing's changed except the caliber of the videos.
