SUMMARY There seems to be a bug where a the style resource is not duplicated when a layer is copy and pasted into the same document. In both 5.0.2 and 5.1 nightly. STEPS TO REPRODUCE 1. Create a layer, add a stroke and a color overlay to the layer 2. copy the layer and paste it into the same document 3. now modify the original one with a different overlay color (you may wish to hide the other layer) 4. save and close 5. open it up OBSERVED RESULT changes to the overlay were not changed. It seems to be keeping a single resource for both under styles even after you change the original. EXPECTED RESULT Another resource should probably be created and changes saved. SOFTWARE/OS VERSIONS OpenSuse 15.3
Created attachment 147433 [details] A sample KRA with layer copied and pasted sharing a resource
I can confirm the issue, but I also get crash -- though that probably is unrelated.
