Fonts are not matched to pixels of display inside lightroom.

Running on Macbook M5 Pro 2026.  MacOS 26.5.1.

Fonts, including the application menu on 4K external display are not rendered correctly.  They look like they are being smoothed for a retina display.  Built-in display on the macbook looks fine.

In the screenshot below, the width of the vertical lines vary depending on position.
