On MacOS the Lightroom Classic Rendering Area appears to show a non-Retina rendering on a Retina screen. The pictures looks pixelated and so does the brush. Every other UI Element has its normal retina sharpness.

Please pay attention to the guitar strings. You can clearly differentiate the pixels. Also the brush shows jagged pixels on the lines.

The issue appeared with an update in 2025 and has never been fixed since.

    I don’t see these symptoms on my Macbook Pro (2023, 16” Retina) or the external 4K display. Without a sample photo allowing Adobe to reproduce the problem, they’re very unlikely to pay attention.

    The file is a standard Fujifilm RAF out of a XT5.  Nothing special here.

    I forgot to mention that the issue is not there all the time. Sometimes restarting does the trick. It’s pretty random.

    This is how it’s rendered after restarting.
