Created attachment 139415 [details] Example buttons vs context menu SUMMARY Both buttons are not doing anything when active layer is a transparency layer. STEPS TO REPRODUCE 1. Create a simple document with one paint layer 2. Add a transparency mask 3. Try to use "Add blank frame" and "Add duplicate frame" with buttons OBSERVED RESULT Nothing happens Use of action in context menu works. EXPECTED RESULT Button should work as context menu :) SOFTWARE/OS VERSIONS krita-5.0.0-prealpha-949e869-x86_64.appimage

Hi This has been changed to "resolved, not a bug"? I'm not sure to understand why... Buttons are not working, it's bug :) Grum999
