Linux, CachyOS(an Arch derivative). You click the frog first time and it properly shows both linear and spring animations with labels. Click again, it just plays the sprite animation as if you just entered the scene. Click frog third time and it shows the labels/animations again. Alternating like that every click.
Oh I see!! This is not a bug, but I could make the frog’s text change when you click on it for clarity!
The paperclip usually works like toggles (on/off), so here you are turning on/off the “compare with linear” mode! Once you click on it, you can just change the transitions directly or press the “Restart” demo to replay the animation (with the “compare with linear” mode enabled)!
