The parent has several children that all need to scale in unison with an Animation. It would be a last resort to try.

FWIW, I ran into a similar issue, and this is the response I got back from Roku when inquiring about it...

In general, scaling text is a very bad idea, as it will get very blocky. The string is rendered using glyph bitmaps based on just the font size, then the resulting bitmap representation of the string is scaled up or down. You’ll get very ugly text if you add any scale in the transformation matrix above it.

Sounds like "it is what it is".

Bonus thought: is there something about the way scaling is done? Akin to ifTextureRequest.setScaleMode, the trade-off speed vs beauty.

Set the font size larger so it's normally scaled down, which should be less of an issue and then the "scale up" is actually the native size?

This still looks bad on screen

I abandoned the whole idea of scaling and switched to active and inactive states for my issue, but... Could you move the label outside of the scaled group, and update the font size based on observing the "scale" field on the group that you're scaling?

I bet it's a bitmap scaling, i.e. everything is rendered to a bitmap first and scale factor is applied only at the very end when plastered on screen. It will work good for fleeting animations but not for static image on screen that needs crisp edges (like font).

I have to say i am confused about <font/> and font= though!

Nodes that use fonts include a field that stores a Font node. The font to use is specified by creating a Font node, and setting its uri and size fields.

Well which one is it - in B/S parlance there is the attribute `label@font` and `label.font`. One is a string, the other can be a list of elements - what happens if both are present or <font/> is repeated? Hopefully not "kaboom"

That is exactly what is happening. So, we finally decided that we're passing on scaling the item.
