I have ubuntu 13.04 and kde 4.11.1
My problem is that firefox scrolling is slow and laggy.
I'll give you some more information:
- Firefox 23.0
- my video card is an ATI HD6870 and I have the FGLRX drivers 13.4 installed
- it's not related to flash because it happens even on web pages where there is not flash
- it's not related to ads because I use plugins to block ads
- it also happens with unity so it's not a desktop environment related problem
- it's not about the number of addons I have installed because I have done a fresh firefox installation and it happens the same and I have the same number of addons on firefox on windows and it works better on windows
- I have tried both these addons for smooth scrolling https://addons.mozilla.org/it/firefox/addon/yet-another-smooth-scrolling/ and https://addons.mozilla.org/it/firefox/addon/smoothwheel/ and the scrolling is worse with them
- I have activated "no tearing desktop" in catalyst control center because I need it when playing mkv movies and "catalyst A.I"
- I have also installed chromium and it's much smoother and faster and I have no scrolling problems with it so
- I also have a notebook with ubuntu 13.04, kde and same firefox version with same addons, it has a nvidia video card and scrolling is much smoother and faster in firefox rather than on my computer with the ati video card
Any advice to solve it?
Thanks

ATI's proprietary drivers are notorious for their bad 2D performance. Unfortunately there is not much you can do about this for now. However, Ubuntu 13.10 will ship with Linux >3.11 which comes with significant performance and power management improvements to the open source radeon drivers, which have always been better at 2D rendering.
I woul advise you to try upgrading to 13.10 when it's released in October. Until then, I fear, you will have to deal with the performance issues surrounding FGLRX.
