Bug ID: 510037
Summary: Editing fill layer quickly crashes krita, because
`m_view` is nullptr in
`KisDlgGeneratorLayer::saveLayer`
Classification: Applications
Product: krita
Version First git master (please specify the git hash!)
Reported In:
Platform: Other
OS: Linux
Status: REPORTED
Severity: crash
Priority: NOR
Component: * Unknown
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
SUMMARY
Example stack trace at the end of bug report
STEPS TO REPRODUCE
1. Create a new moderately large document (e.g. 10000x10000 pixels)
2. Add a fill layer, choose simplex noise, set frequency to 500, click OK
3. In the Layers docker, right-click the fill layer created in step 2, and
select Properties. Change the frequency to another high value (e.g., 490),
click OK
4. Krita would crash, if not, repeat step 3, and maybe try click faster
OBSERVED RESULT
EXPECTED RESULT
SOFTWARE/OS VERSIONS
Qt 6.9.2, recent krita git master
