This is my dmesg log after I tried to scroll in dolphin.

My Xorg.0.log file.
This should be fixed in 6.13.0 assuming the issue is GetImage performance. 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. Created attachment 35452 [details]
oprofile output when scrolling in dolphin
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. Mass closure: This bug has been untouched for more than six years, and is not obviously still valid. Please reopen this bug or file a new report if you continue to experience issues with current releases. |

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.
