Red Green And Blue blinking dashes near tab windows on borders.
I have been seeing few dashes/hyphen like colored lines moving on the top of my web browser screen randomly in order only on the top border of the browser. Was wondering if this happens generally for FIREFOX QUANTAM users on Mac. I have been seeing this only on this browser. I have also attached the area/region where it occurs for reference. However, whenever I try to take a Mac Screenshot with the particular dashes it suddenly disappears.
I hope someone knows about this. Looking forward to some help.
