NSSegmentedCell misplaced in Liquid Glass mode (macOS 26)

We are currently testing our application under macOS 26 in Liquid Glass mode and noticed an issue with NSSegmentedCell.

Our app makes extensive use of NSCell-based drawing. Since macOS 26, when running in Liquid Glass mode, NSSegmentedCell does not render at the expected location.

The control itself appears visually correct, but it is clearly drawn offset from the rect it is supposed to occupy. In compatibility mode, everything renders exactly as expected (same code, same layout).

To illustrate the issue, here are two screenshots of the same view: Liquid Glass mode 👉 (screenshot 1 – segmented control visibly shifted) Compatibility mode 👉 (screenshot 2 – correct rendering)

The regression is obvious when switching between the two modes.

This behavior has been present since the first macOS 26 release and is still reproducible with Xcode 26.2 (17C52).

I have already filed a report via Feedback Assistant (FB reference available if useful), but I’m posting here to see whether others are experiencing the same issue or have found a workaround.

Thanks.

Hello @PatPol,

I'm interested in taking a look at that FB report, do you mind sharing the FB number below?

I'll make sure it's on the right path. And If there's a sample project attached I could possibly offer direct workarounds, or feel free to provide code in this thread.

Thanks!
