Thanks for the report, but there is not much I can do against this issue: The scrolling is fully handled by Qt, which delegates it to the graphics driver... Could you please give more details regarding: - Which view mode are you using (icons, details, column view)? - How is the scrolling done: with the mouse using the scrollbar or with the keyboard? - Which Windows style are you using? Oxygen? If yes: Does turning into a more simple style improve the performance?

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. > I should note that the invoking menus of Dolphin using the Alt+F

This is very strange: Dolphin uses KDE standard menus like KMail... Do you have performance issues in other KDE4 applications too? E. g. KWrite? Also it would be interesting if you face similar performance issues in the file-open dialog (please maximize the dialog to the same size as your Dolphin window to have a fair comparison). Thanks!

I have in the Konqueror file browser. KWrite takes some time to start on a relatively large file, and emits many warnings upon every keypress, but otherwise the scrolling there is fast. > Also it would > be interesting if you face similar performance issues in the file-open dialog > (please maximize the dialog to the same size as your Dolphin window to have a > fair comparison). Thanks! After I adjust the size of the file-open dialog to be large, and explicitly select the Detailed view, then scrolling there becomes sluggish too. Thanks for the update. I'm sorry to say that I cannot do anything against this (the file-open dialog contains no Dolphin code). This is most probably a graphics driver issue (I faced a similar behavior during KDE 4.0/4.1 with NVidia). Thanks!

Version: 1.3.80 (using Devel) Compiler: g++-4.4.2 OS: Linux Installed from: Compiled sources 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.
