Bug ID: 518299
Summary: Table view unusable during background scan: selection
cleared and scroll position resets
Classification: Applications
Product: digikam
Version First 8.8.0
Reported In:
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Database-Scan
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
SUMMARY
While the database is being scanned (large collection, partially stored over
NFS), the "Table" view becomes practically unusable.
In this state, it is not possible to reliably select items or maintain scroll
position.
I suspect this is a regression, although I do not frequently use the Table
view, so I cannot pinpoint the exact version where the behavior changed.
STEPS TO REPRODUCE
1. Start digiKam and let it scan the database (automatic on startup in my case)
2. Switch to "Table" view
3. Use any collection view (Albums, Tags, Labels, Dates, Timeline, Map)
4. In the table:
a. Try selecting one or more items
b. Scroll vertically or horizontally (e.g., to the middle of the table)
OBSERVED RESULT
a. The selection is cleared almost immediately (within ~1 second)
b. The scroll position resets:
- typically to the start
- or to the end if Ctrl+End was pressed previously
This appears to be related to model/view updates triggered by the background
scan, possibly causing the view to be reset repeatedly.
EXPECTED RESULT
a. Selection should remain stable until explicitly changed by the user
b. Scroll position should remain stable
NOTES
- The issue only affects "Table" view
- Other views ("Thumbnails", "Preview", "Map") behave correctly
- The problem occurs consistently during background scanning
- The collection is large and partially stored over NFS (may or may not be
relevant)
