Inconsistent text scaling when changing screen aspect ratio.

Unity Engine

Hi.

I noticed if you set the Canvas Scaler to “Scale With Screen Size” and have a text field with it’s contents spanning more than one line, the text size varies as it adjusts itself to the new screen size when you change the aspect ratio.

Is this an expected behaviour?
Here’s a GIF that better explains the situation.

Cheers.

Yes, this is expected behavior.

The text renderer we use in 4.6 is fully bitmap based and can only render fonts in size increments of one whole pixels at a time. So we pick the nearest size for the given Canvas scaleFactor.

This solution is far from optimal, but it was out of scope to rewrite the text renderer for 4.6. We’re planning to replace it with a better approach in a future release.

Thanks, runevision. That’s good to know.
