    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:

    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?

    Isolate a hardware/ software issue. Boot to internet recovery and choose "get help online", go to youtube etc and see if the issue persists using freshly downloaded recovery OS.
