Zoom is doubled

[whiteonline]

On MacOS, I am finding that selecting 100% zoom results in 200% actual zoom. I must select 50% zoom to accurately view 100%. I have compared this to Capture One and Photos. The other two programs match the output at 100% while Lightroom matches at 50%.

Anyone experience this?

Are you running Big Sur? This zoom doubling has recently been identified as a bug, but only on Big Sur so far.

Ah. That's what it is then. Yes, Big Sur.

Appreciate the response.
