Description

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.

See JDK-8252649 for another test case.

Hi Kevin, In continuation to your previous comment, I am removing the regression label.

Prior to JDK 9 we didn't enable Hi-DPI for systems with 125% scaling. So even though this is technically a regression, it's probably more accurate to say that this is a bug in a new feature.

Looks to be a regression, Issue reproduces with 9 GA, but does not reproduce with 8 GA / 9 b90. Need to bisect JDK 9 builds.
