Bug ID: 479606
Summary: OverlayDrawer crashes when setting modal from true to
false if drawer is visible
Classification: Frameworks and Libraries
Product: frameworks-kirigami
Version: Master
Platform: Compiled Sources
OS: Linux
Status: REPORTED
Severity: crash
Priority: NOR
Component: general
Assignee: kdelibs-b...@kde.org

Target Milestone: Not decided
Created attachment 164785

Basic QML file showing how to reproduce the crash in pure Qt. Not sure if this
is a bug in Qt or a misuse of Templates.
SUMMARY
When the OverlayDrawer is visible and modal is changed from true to false, the
app crashes. The crash can be fixed by inheriting from QtQuick.Controls.Drawer
instead of QtQuick.Templates.Drawer. I'm not sure if this is a bug in Qt Quick
or if Kirigami is misusing the template, hence why I'm reporting the bug here.
I've attached a minimal Qt-only demonstrating the issue. Run the code and press
the button twice and the app will crash. Swap T.Drawer for C.Drawer and the app
works just fine.
In terms of apps the issue can be reproduced in Koko:
1. Run app in desktop mode
2. Reduce the window width until the sidebar hides and becomes modal
3. Increase the window width
Observed result: app crashes
Expected result: non-modal sidebar re-appears
Can also be reproduced with the Sidebar.qml example provided by Kirigami.
