Motion Blur artifacts macOS 10.15.6

Greetings to community. I have a problem with layer style effects. After creating a heart shape in AI i moved it to PS. Then made a smart object of it and applied the following effects (layer styles and then motion blur). As you can see shape edges (left one) get box style crop. Have anyone experienced this issue?
P.s no crop was added by me. Tried restarting and there's no performance issues. Mac OS 10.15.6
