during segmentation I’m getting this annoying blinking whenever effect is applied like the model disappears and returns in seconds. sometimes less sometimes more. first time i thought i deleted the segment. mostly noticed with smoothening brush

Which Slicer versions do you experience this with? Can you check both latest stable and preview releases? Can you take a screen capture video of it?
