Description

Description of the Issue

Font rendering produces artifacts on 2560x1440 screen, see screenshot, pixels between words in the middle, there are 2 half-visible lines.
изображение

I don't have any software scaling enabled, it's set to 100%.

Sometimes Firefox has the same issue, but mostly depends on the website.

Other programs on PC work fine and do not produce artifacts.

If I scale font up the issue is going away.

Research direction

No source file, test, or entry point is named. Start by reproducing the artifact on Windows 10 at 2560x1440 with 100% scaling using the supplied screenshot and debug information; done means the half-visible lines between words no longer appear without changing font size.
