Font Scaling Issues in 4.X

EthanCranmer — Thu, 28 Dec 2023 20:26:26 GMT

When switching from ArcGIS 3.35 to 4.28, we're having trouble with the font not scaling to as large of a size and it also begins to look blurry. Is there supposed to be a font size limit for 4.28? Is there a way to change how the font is rendered in 4.28 to be more like it was in 3.35?

Below are two examples, one in 3.35, the other in 4.28, with the same font settings (size 400pt). However, the 3.35 text is much sharper and is also larger.

Code sample 4.28:
