Description Shlomi Fish 2009-12-18 11:06:01 UTC 
Reading from the KDE bug report:

<<<<<<<<<<
Scrolling in Dolphin is very sluggish with the radeon ("ati" or "video-ati")
driver with DRI enabled. I recall it being much better with "Option NoDRI". I'm
using the radeon driver from git close-to-master, and on Mandriva Linux Cooker.

I have an ATI Radeon HD 2600 Pro AGP graphics adapter on a Pentium 4 2.4 GHz
machine with 2.5 GB of RAM.

It happens with details using expandable directory-sub-trees. 

I'm using the IaOra widget style and windows' style. But this also happens when
running Dolphin on top of XFCE.

I should note that the invoking menus of Dolphin using the Alt+F ; Alt+E , etc.
in the keyboard is also sluggish. KMail seems to work fine in both regards.
>>>>>>>>>

It was also verified to happen in the Open file dialog.

I'm using radeon from git master.

Comment 5 Alex Deucher 2010-05-05 07:50:30 UTC 
This should be fixed in 6.13.0 assuming the issue is GetImage performance.
Comment 6 Clemens Eisserer 2010-05-05 14:13:50 UTC 
I really wonder why QT is doing so many GetImage requests at all.
However last time I checked, their X11 backend was in a horrible state.

oprofile output when scrolling in dolphin
Comment 8 Martin Stolpe 2010-05-06 01:43:59 UTC 
Scrolling in dolphin consumes still a huge amount of cpu power. But I don't think it's related to the graphics driver. I'm also under the impression that there is something going wrong in what qt is doing. As usual I created an oprofile log. Unfortunately I can't get qt compile with debug symbols.

obviously still valid. Please reopen this bug or file a new report if you continue to experience issues with current releases.
