This will be difficult to explain, the reason why I had no luck simply Googling the issue. Some sites that I frequent, Reddit the largest culprit, contain links or buttons that perform a function on the page (the collapse/expand thread button). When clicking this button, sometimes things work perfectly, other times, it will do the desired action then upon moving my mouse, part of the page gets over taken by a large white block that seems to be laying on top of the page. I can remove this effect by highlighting the area or retrying the button a few times and eventually things will resolve. Other times, such as filling out this text field. The text line indicator will jump back and forth between where I'm actually typing and a few words behind from where I actually am. It won't delete my text, just not show it for a short period of time. As you can tell, this is all aesthetic, not really functional. I've tried a Flash reinstall but no help. Anyone have any ideas or can relate any way?
