2019 PS Compositing Engine Inconsistent and Unusably Buggy. It clips things depending on zoom scale and exactly how one clicks or uses tab to navigate fields. Please have real people test your software. All of this was immediately noticeable to me.
I encountered so many bugs with masks on smartfilters not working when you save that inside a smart object it's not applied to the smart object above. blur a layer also blurs layers mask instead just blurring and masking out. display errors when zooming or not updating changes on screen etc.
