            Bug ID: 349975
           Summary: Import window freezes when selecting multiple items
                    and scrolling
           Product: digikam
           Version: 4.11.0
          Platform: Other
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: Import
          Assignee: [hidden email]
          Reporter: [hidden email]

I have a special performance problem / huge lag when importing from my SD card
reader (UHS-I, USB 3.0, card used in a Canon 6D but transfer is over USB
cardreader).

Reproducably, when selecting some 10+ items and then trying to scroll down
(using mouse wheel or scrollbar), the import window hangs for 10-20s, then
continues to work normally.

Did you enable some options in Setup/Camera/Behavior dialog page ?

I use SD card too with plenty of files : 32Gb SDCard used with a Sony A77. No
time latency problem here...

--- Comment #3 from Maik Qualmann <[hidden email]> ---
The problem was the isSelected(KURL) function. Number of selected items * this
function was very time consuming. The selection of 1000 new items has needed
more than 20 seconds now no one second.
