As asked by @eoinoneill I created a new bug instead of use the closed bug that I’ve re-opened
https://bugs.kde.org/show_bug.cgi?id=438760
And I confirm the bug is related to autosave action.
- If autosave is deactivated, bug doesn’t occurs.
- If autosave is activated, bug occurs.
- If autosave is activated and document is not in modified state when render is started, bug doesn’t occurs.
Maybe it’s no autosave, but it seems strongly related.
Here a video of what happen:
Note: to ensure failure is not related to frame clone limit bug, I’ve set the number of clone limit to 4 (then, I know that when autosave is disable, with 4 CPU krita is able to render animation)
