This started happening around a week ago and has got progressively worse.
This happens only sometimes and has only happened three of four times. Although when it does happen each time the effect observed is greater.
A quick reboot has fixed the problem. However, I'm afraid that this is the symptom of a more serious issue.
What should I do to diagnose and fix this?
And the following happened after @Dan answered the above:

Best Answer
This means your video card or motherboard is failing -- if your Mac is still under Apple Care warranty, you're set. If not, it'll cost you $$ to fix. Take it to an Apple store or Apple certified repair shop, as it's nothing you can fix yourself. Yes reboots will help temporarily but it will get progressively worse over time, in my experience. The good news is that your data is fine.
