Yesterday I got an RX580 to output 4k video on a 288p Phillips monitor. After messing around with scaling and everything I got to a point where i'm satisfied, but I've come across these weird glitchy green artifacts when fullscreening a 4k video on YT. It does go away alfter a second or so, but it happens most of the times I hit the fullscreen button. The image also gets immediately washed out and a little undersaturaded as soon as I hit play (I'm able to perceive the instant switch in colors). I haven't noticed any other bugs for now, games appear to work just fine and I tried installing 3 different drivers with no result. I did disable hardware acceleration on chrome, and the green stuff went away but I'm not quite happy with the general 'lagging' and stutteriness of the browser after that. Any advice on how to overcome it? I'm using a high speed HDMI cable, which I already swapped for another one still with no luck. DP is not an option right now, as I won't be able to get ahold of a cable to test it until next week. I was able to capture the green glitches on video, so I could provide an imgur link with an example, if allowed by the forums rules. Thanks in advance.
