A bit of information for you to aid in your troubleshooting (if needed).
ISSUE: Chrome Browser using either FVD Speed Dial, or Speed Dial 2 (perhaps more) your thumbnails become skewed and distorted upon refreshing them.
After having spent the last 2 days sobbing uncontrollably over my keyboard trying to find a solution for this problem I happened upon a thread somewhere that solved it.
Don't waste your time uninstalling apps, checking video drivers, etc. The problem is in the latest version of Chrome.
Mine is at Version 26.0.1410.43 m.
I installed Chrome Canary and the problem is not present. Unfortunately, Roboform does not work with Canary. That is a no-go for me as I rely on Roboform heavily.
In any case, word has it that if you wait a few days that the next Chrome update will fix the issue.
