Bug ID: 524674
Summary: Details view tree expand/collapse indicators are
missing until view is reinitialized
Classification: Applications
Product: dolphin
Version First unspecified
Reported In:
Platform: Fedora RPMs
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: view-engine: details mode

SUMMARY
In Dolphin 26.08.0, the tree expand/collapse indicators and branch graphics in
Details view are frequently missing when a new view is created.
The issue appears to be per-view/per-tab. Changing the zoom level restores the
indicators for the affected view. Switching from Details view to Icons view and
then back to Details also restores them. However, switching from Details →
Compact → Details does not restore them.
Opening a new tab after fixing the current tab can reproduce the missing
indicators again.
STEPS TO REPRODUCE
Open Dolphin.
Use Details view in a directory containing folders that can be expanded inline.
Observe that the expand/collapse indicators and tree branch graphics may be
missing.
Change the zoom level by one step.
Observe that the indicators immediately appear.
Alternatively, switch Details → Icons → Details; this also restores them.
Switch Details → Compact → Details; this does not restore them.
Open a new tab; the new tab may again have the indicators missing.
ACTUAL RESULT
Expand/collapse indicators and tree branch graphics are missing in newly
created Details views/tabs until the affected view is reinitialized by certain
actions.
EXPECTED RESULT
Tree expand/collapse indicators and branch graphics should be rendered
correctly immediately when a Details view or new tab is created.
ADDITIONAL INFORMATION
Fedora 44 KDE Plasma
Dolphin 26.08.0
Plasma 6.7.4
KDE Frameworks 6.29.0
Qt 6.11.1
Wayland session
Changing zoom fixes only the affected view.
Switching Details → Icons → Details fixes it.
Switching Details → Compact → Details does not fix it.
Opening another/new tab can reproduce the broken state.
The problem has occurred regardless of whether Dolphin was launched from a
terminal or via the Meta+E shortcut.
I also saw this Dolphin journal warning during testing:
QLayout::removeWidget: Cannot remove a null widget.
However, I do not know whether that warning is related; it has also appeared
after the visual issue was already corrected.
