So I have a multiline text that has the "Justified All" property set for text alignment.
As you can see in the video, depending on the zoom level of the viewport, the text behaves in a weird manner. As if at some zoom the text is displayed as expected, at some other zoom the first line ignores the Justified All property, and in between there is a glitch that displays half of the text correctly, and half of the text wrong.
When exporting, with these dimensions, I got the half/half result. This issue was pretty annoying, and my workaround was to create multiple text layers instead of one multiline.
I included the .afphoto document to this thread, as well as the video and screenshot I posted on Twitter.
Hope this helps to investigate the issue, as it is very annoying.
