When going to certain websites, the websites wobble up and down. The same thing happened installing it on standard Vista RC1, so this is not exclusive to this installation. Its a difficult problem to describe and not one that can be shown in a screenshot so I have made a video of it which you can view here www.photoscene.co.uk/wobble.avi the filesize is only about 4.4mb Please note the shaking is not my hands shaking, it is actually a wobble on the screen. Apologies if this is a duplicate but although I did search, it was difficult to put it into words. Reproducible: Always I am not sure I can put in steps to re-produce the problem. As you can see from the short video, its not one that I can get people to reproduce, its just a wobble up and down of some pages. I am struggling to verbalise this problem and explain it well to produce a good bug report, but as hopefully you can see from the video, it just wobbles and makes browsing difficult, although it does not happen on all sites :-/

duplicate of bug 247116 ? Reporter, it would be very useful if you could provide an URL where this happens.

I have checked a few of my favourite sites and this happens on www.google.co.uk www.bbc.co.uk www.eurogamer.net www.gamespot.com I can keep posting websites it happens to if you like but there are a few examples. One thing I did not notice before and should have mentioned was the wobble always starts after the page has finished loading, so sometimes the wobble is not evident immediately.

I have just looked at the possible duplicate bug, and while the symptoms are the same, I have to point out that the only thing I have done to the toolbar is to remove the two default links added - latest news and the other one which upon installation are shown default on the links bar.

Update yes indeed this is a duplicate of the mentioned bug. I have managed to follow the steps advised and added a new link to the toolbar. The bounce has now gone. I shall close this bug as a duplicate. *** This bug has been marked as a duplicate of 247116 ***
