Hi ,for the past 3 weeks at various times when waiting for a Youtube video to appear,a thin red line appears at the top of my screen just below the Chrome browser search bar (see pic I made below).The line usually scrolls across my screen when I have clicked on another video and I'm waiting for it to appear,as if it's a loading symbol.
This line does not always appear though,one day it's there next it isn't and so on.. .it also doesn't seem to correlate with the length of time I'm waiting for Youtube to load.I've tried searching about,thinking it might be some new Youtube changes or glitches but haven't found any information regarding this.
Any help or info would be most appreciated..Thanks
