☝🏻This demonstration seemed provoked only while scrolling, though in other testing I noticed it happening without scrolling, also. It seems that some triangles are being rendered outside the target area?

NI'ing :gw for more info. on this.

This doesn't seem like something that would cause a person to switch browsers. Marking as S3
