I was suspecting the same @MaxZieb mentioned and I ungrouped the two lines of the headline – look at the elements in the main timeline. Having done this, I unfortunately can't see any changes in Chrome's weird render bug.
Some versions back Chrome overtrumped Firefox in smoothness of rendering of animated live text. Now Firefox Quantum got rid of its annoying render bug, but Chrome seemingly have caught on that.
I would love to have the possibility of converting text to a png with alfa inside Hype.
