UI Scaling (downwards) overshooting v. Cubase 14

On Windows 11 at 2560x1600 and system scaling 125%, Cubase 15 at -25% scaling appears smaller, with text marginally blurry in comparison to Cubase 14 also at -25%.

The horizontal separation lines between track headers are also intermittently missing in Cubase 15, which indicates aliasing. HiDpi is on, so that’s not the problem, with HiDpi OFF the blurring is way more severe

When scaling is set to “Use System Settings”, the two versions appear identical, so it would appear that the new scaling backend in 15 is “overshooting” the downscale somehow.

You can compare the two attached screenshots.

Is this a known issue?
