           Summary: Rubberband not smooth in dolphin
           Product: kde
           Version: unspecified
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: unassigned-bugs kde org
        ReportedBy: j053f.k gmail com


Version:            (using KDE KDE 3.5.8)
Installed from:    Ubuntu Packages
OS:                Linux

When I select multiple files/folders by holding down the left mouse key I notice that the rubberband motion is not smooth at all and it glitches.
I only experience this in Dolphin. On the desktop or in Konqueror the movement is very fluid.

The problem is still there. KDE4 svn of yesterday, build myself, on gentoo.
I can clearly see the difference in selection speed between dolphin and konqueror on my system (core duo cpu and nvidia 7300go gpu). KWin compositing (3d effects) makes no difference.

To reproduce :
open dolphin, go to a folder with some images, activate "preview", drag the rubberband around -> result : the selection lags quite bad behind the mouse mouvements

open konqueror, go to the same folder, drag the rubberband around -> result : the selection (almost) smoothly follows the mouse

Visually, the two behave identical, it's just the speed that differs.


Imortant : Using a folder with images, with preview on, highlights the speed difference, but the difference exists under all circumstances (even with preview off, in a folder like /lib).


Konqueror uses the dolphin-kpart, so the problem must be in dolphin itself (not the kpart). 

This bug is really annoying, because dolphin gets just to slow to use confortably ...
