Hello, When watching a video on YouTube, with chromium based browser (opera, edge chromium, chrome), the video is smooth, however when scrolling with the video on the screen, there is a lot of stutter, with vp9 and h.264 codecs. Making the browser run on my mx150, resulted on a very smooth experience (tested only on opera, with vp9). On Firefox, everything is smooth with the uhd 620. I tried Dailymotion, it was a lot smoother, but with chrome and opera, it seemed to be a bit of stutter.
My config : i7 8550u (with uhd 620, latest driver)
16go ram (dual channel)
hardware acceleration enabled (on enabled when possible)
