I’ve been trying to reproduce the issue on my system (Win 8) but haven’t been able to. Let me test it on Windows 7. By doing a quick search on Google I found out that others are facing similar issues on Chrome 29 – I tried & even this issue doesn’t seem to exist in incognito mode. Also, it has been fixed in Chrome 30 it seems. Anyway, I’ll try reproducing this issue on other OS and fix the problem at the earliest.
Does your system have Nvidia graphics cards??
