Currently, rotated UI elements (ex. TextLabel, TextButton) are aliased or blurred, causing some sort of focus on users and developers that use rotation for UI. Extremely bothersome to me.
To me, or other developers, it can be bothersome to eyes or trigger ourselves, I’d like it if it wasn’t so blurry at all, having it at zero makes it crystal clear.
If you really need a workaround for this you can take advantage of texture interpolation and make the border built out of a texture that has a couple extra transparent pixels around the outer edge. That way the actual aliased edge will be invisible, and you will see an apparent edge with some amount of anti-aliasing.
The downside is that requires you to use a dedicated texture tuned to the border width that you require and makes you consider that extra transparent boundary space layout wise.
