Snipping Tool Bug

One of the most useful ‘powertoys’ of the Tablet PC is the Snipping Tool. It allows you to take a screenshot of your screen and annotate on top of it.

However, I’ve spotted a pretty major and severe bug with its capturing ability. It seems to affect all JPEG images. When your screen contains any rendered JPEG images, may it be in a browser or Windows Picture and Fax Preview, the JPEG image becomes artifacted with white lines. On some images, the lines are very small and only about 2px long. However, on other images this problem is very visible, as shown below.

I will forward this to the Tablet PC team at Microsoft, perhaps they can shed some light on this.
