For quite a long time I've been experiencing strange behaviour every time I watch some online videos. I have literally no idea how to describe it, so I recored it. Here is some basic info: 1) it happens always, but sometimes it's all the time and sometimes just every few minutes; 2) it happens on all sites (Netflix, YouTube); 3) if I move my mouse it disappears (you can see it on my video); 4) it does not happen when I use screen recording software, NEVER (tried to capture it that way); 5) it always looks the same; 6) happens in every browser; 7) video software like VLC works fine; 8) it wasn't always like that. For some unknow reason I cannot attach my video, so here is the link: https://streamable.com/iw6se I know the quality is rather bad, but it clearly shows my problem. This is extremely annoying and I'm not even sure what should I search for. Does anyone have an idea what might be the problem? Have you ever experienced something like that? Did you solve it?
