Research direction

Start by reproducing the artifact with the linked Rive file and the listed @rive-app React canvas and WebGL packages, testing the edge-scaling cases shown in the video. Compare behavior across the listed browsers; done means the visible line artifacts no longer appear when the Rive element edges meet the parent element.

Description

triage

Hi folks,

We've noticed an issue. When the rive element edges are visible to the parent element, we get some line artifacts. It was the same on top/bottom and left/right (depending on how we scaled it).

Here's a video of the issue:
