To reproduce this, run the attached test program on a Windows machine with HiDPI scaling set to 125%.
The text in the Label and TextField is crisp, while the text in the TextArea is blurry. This may be a layout bug or a bug in the TextArea relating to the positioning of its content such that snap-to-pixel isn't working properly.
I have attached an image as well. If you zoom it up you will see that LCD text is used for all three strings.
