Re: [compiz] Slow Scrolling in Compiz
*It is* a driver issue. Sometimes downgrading the driver to version 8.40 can help (but I don't know if your card is supported). Regards, Pierpaolo On Thu, Mar 6, 2008 at 3:34 PM, David C.

Rankin [EMAIL PROTECTED]: Listmates, Hopefully this is a compiz only question. Using the mouse wheel to scroll down web pages seems to be much slower in compiz than in kde.

Sorry Clemens, I should have included the specifics. The system is a Toshiba P35, P4 3.3GHz, 2G RAM, ATI Mobility Radeon 9600/9700 series running openSuSE 10.3 with the ATI 8.45.5 driver. I don't think it is a memory overhead issue. I have looked closely at this with top/free -tm and compiz adds no more that 20M of memory overhead which wouldn't be an issue here. The slowdown in scrolling I am talking about is by a factor of 2-4 times slower than without compiz. With kwin, rolling the mouse wheel to scroll web pages or konqueror directories results in immediate and crisp scrolling of content either up or down depending on wheel rotate direction. With compiz there is a notable delay in the time between wheel input and scroll response (on the order of milliseconds ~ 400 or 500). The scroll delay problem is much improved with the latest 8.45.5 driver with the delay between wheel input and scroll decreasing greatly, but it is still noticeable. Testing now in response to your post, this is much improved over the 8.43 and earlier drivers. This leads me to suspect it may be more of a driver issue than a compiz issue. I will test with the 8.47 driver later today or tomorrow and report back. -- David C. Rankin, J.D., P.E.

Regards, Pierpaolo Thanks Pierpaolo, The 8.45.4 driver is really much, much better than earlier drivers. So hopefully AMD will continue to work on the issue. -- David C. Rankin, J.D., P.E.
