Bug ID: 414668 Summary: Crash with onion skins when using opacity keyframe on a layer with non-animated content Product: krita Version: nightly build (please specify the git hash!) Platform: MS Windows OS: MS Windows Status: REPORTED Severity: crash Priority: NOR Component: Animation Assignee: krita-bugs-n...@kde.org Reporter: ahab.greybe...@hotmail.co.uk Target Milestone: --- Created attachment 124189 --> https://bugs.kde.org/attachment.cgi?id=124189&action=edit Example .kra file to induce the crash SUMMARY This happens with the latest 4.3.0 prealpha Windows build g5924da4972 and also the 4.2.8 Linux appimage. STEPS TO REPRODUCE 1. Put opacity keyframes on a layer which is not itself animated. This may be done to give some kind of fade in/out effect for the layer content. 2. Click on the onion skin icon for that layer in the Timeline docker. A .kra file is attached that illustrates this. OBSERVED RESULT Crash I attach the Windows crash log. EXPECTED RESULT Not crash I know that there's no point in trying to show onion skins for this situation but if it can be done them somebody will try to do it (like I did). A workaround is to make one animated frame by using Create Duplicate Frame on frame-0 of the Timeline so it fills up with held frames of the layer content. However, this can't be done if an opacity keyframe has been placed on frame-0.
