I have a kind of... very odd problem I've noticed with Chrome as of late.
First off, web pages started lagging ever so slightly -- i.e. if I swap from one tab to another, the page for the tab I am switching to will remain blank for a few seconds. Same for closing tabs, it's just general lag but I'm not sure what is causing it! Around the same time, this weird graphical error started occurring - when I right click anywhere in Chrome to bring up a menu (or if I click on a folder in my bookmark bar, for example), mousing over lines causes them to go invisible until I mouse over them again.
A couple of examples below...
Any ideas?
