(Notes 8.0.2) - Internal Browser triggers high CPU load and some strange behavior while scrolling

In 8.0.2 I have a problem that I had also with 8.5 Beta 1. When I open the internal browser - read Ed Brills blog for example - it takes all the CPU and the computer (ThinkPad R52) is literally blocked.When the pages finally loads - takes long - I have problems to scroll. If I just click on the arrows of the scroll bar, it scrolls slowly all the way up or down.

When I try to post a comment on that blog, it is almost impossible to type a word. It takes several seconds until a letter appears and if I type more then one in a row, some are just lost.

I really liked the internal browser until now, but I can not use it anymore.
