It seems that text is rasterized and displayed as a textures. This makes them non resolution independent. Is there any way to switch between text as textures and text as tesselated shapes at a certain text size?

Fonts are resolution independent, although glyphs are cached in textures. But you can zoom in/out and the text should adapt perfectly. The problem is that when a glyph is too big (more than 256 pixels) it should be rendered as triangles, but in this beta that change does not happen and you are probably seeing a blurred glyph, right? Do you need glyphs rendered at that size?

As a temporal fix, you could convert the text to shapes.

Tell me more about you scenario. thanks.

Yes I am seeing a blurred Glyph at large glyph sizes.
Not at the moment, was just testing resolution independence and was wondering if this was a intended behaviour.
