RT 3.8.0 painfully slow on Firefox / Ubuntu

Hello,
I installed RT a few weeks ago, on Apache/Centos, and while its functions
appear to all work correctly, a big problem is that ticket display screens
are rendered painfully slow if using Firefox on Linux. On Windows, using IE,
everything is snappy, Firefox a bit sluggish, but on Linux scrolling three
pages down in a window renders like a 486 computer opening myspace. I have
checked CPU and memory usage - no signs of overload there, disabled add-ons
and plugins, again no noticeable increase in speed. Can you suggest what
causes this slow redraws? It looks like a Javascript issue, should I blame
prototipe? scriptaculous? Any suggested ways to search for what freezes the
interface?

Thank you

Actually, it’s an interaction between firefox’s corner rounding CSS
and your X server. We’ve seen it on about 3 machines, but never
managed to track it down.

Here we ended in commenting all “-moz-border-radius:” and
"-webkit-border-radius:" in web2 css. With this, we got good
performances on FF.

You can also try to disable the background image gradient.

Hi all - a confirmation: disabling rounded borders solved the slow scroll
issue.
