Public bug reported: Hello,
the problem I'm reporting here is actually a weird interaction between the Nvidia propritary driver, Firefox and Unity, so I'm not sure if I should have reported it against Firefox or Nvidia driver instead. With the propritary Nvidia driver installed, the following happens: - When I visit certain webpages in Firefox, scrolling through them/interacting with them becomes very slow and laggy. The most prominent example are all kinds of paged from launchpad.net, e.g. https://launchpad.net/ubuntu/+bugs, or a random bug report page. This problem exists as long as I can remember (5 years?!), regardless of the version of Firefox or Nvidia driver. - In Oneiric, there is an additional interaction of this slowness/laginess with Unity: If one of those "slow" pages is opened in Firefox as currently selected tab (e.g. a bugreport) and I press 'Super' to reveal the dash and launcher, they take a rather long time to appear in contrast to the normal behaviour and the animation is also slow and laggy (if the dash has come up, it works fine and sleek as usual, so it's the process of the dash/launcher coming up that is slow). - Interestingly I don't experience this slowness of dash/launcher if I reveal them via mouse (hovering to the left screen side and clicking the dash button). The slowness of certain webpages only happens in Firefox (not in Chromium for example), and only if propritary Nvidia drivers are installed, with Nouveau drivers this "slow pages" phenomenon disappears in Firefox too. The additonal problem with the Dash in Oneric may seem small, but it can be rather annoying when trying to write bug reports for example. In Natty there is no such slowness when opening the dash via 'Super' and a "slow" web page is opened, so I reported it to Unity in hope that there may be an easy workaround. But the best thing of course would be if this "slow pages" issue would be fixed in Firefox and/or the Nvidia driver (the latter is of course beyond control of anyone not working for Nvidia :-( ).
