Copied
Hey Adobe team,
I’m running into two frustrating issues since updating to Lightroom version 8.5.1 (Windows 11, AMD Ryzen 3 5425U with Radeon Graphics).
1. Copying masks doesn’t copy exposure settings anymore.
When I copy a Radial Gradient from one image to another, it brings over the mask shape perfectly — but none of the actual settings come with it. The exposure, contrast, highlights, etc., all reset to zero on paste.
I’ve tried:
Copying via the Masks panel (“Copy Mask” → “Paste Mask”)
Copying full edit settings (Ctrl+Shift+C / Ctrl+Shift+V) with “Masks” checked
Same result either way. It used to work fine in older versions — I could paste a radial gradient and it would bring over all my exposure adjustments exactly.
2. Lightroom feels really slow now.
I've always had issues with the program being SLOW, but everything from moving sliders to switching between photos has noticeable lag; even more irritatingly slow than before. It’s especially bad when I’m working with masks. Turning off GPU acceleration helps a little, so I suspect it might be related to the integrated AMD Radeon graphics driver, but performance is still rough overall.
System info:
Windows 11 Home
AMD Ryzen 3 5425U with Radeon Graphics
8GB RAM
Lightroom 8.5.1 x64 (Aug 21, 2025 build)
It feels like something broke with how masks are copied in this version, and the performance drop has made editing pretty painful. Would love to know if this is a known issue or if there’s a fix in the works!
Thanks for taking a look - I really rely on that copy/paste mask workflow, and it’s been a huge timesaver until now.
