Summary: RGB parade is blank after restart
Classification: Applications
Product: kdenlive
Version First 25.12.2
Reported In:
Platform: Kubuntu
OS: Linux
Status: REPORTED
Severity: minor
Priority: NOR
Component: User Interface & Miscellaneous
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
SUMMARY
The RGB parade scope is completely empty if Kdenlive is restarted.
STEPS TO REPRODUCE
1. In an active project (with clips in the timeline) enable the RGB parade
scope: View -> Scopes -> RGB Parade.
2. Verify that it shows something (move back and forth in your timeline and
observe that the scope works).
3. Exit Kdenlive.
4. Start Kdenlive and choose a project to load.
5. After Kdenlive finished loading the project go to the RGB Parade widget. (It
should still be enabled.)
OBSERVED RESULT
The window is just empty showing nothing.
To fix it, disable it in the menu (View -> Scopes -> RGB Parade) and enable it
again. It will then just work fine again.
EXPECTED RESULT
The RGB diagram shall be shown.
