A big help since i am using clarity to blurry my backround.

Possibly have lens blur in the drop down on the AI masking tool so it selects the background automatically

It's amazing, if you can blur the edges when you rack the foreground obect out of focus, it would be great. Right now its sharp edges it needs to blend with the background.

The edges do not blend naturally into the background from the foreground.

I have a pretty fast computer with plenty of ram and a good video card. Using this feature, every time I make any type of adjustment, it temporaraly crashes lightroom and says up in the corner, "not responding", then after a few long seconds, it comes back and seems to be okay. But this will be a huge problem if it continues without and update fix.

Windows or Mac? If on Windows, follow https://helpx.adobe.com/lightroom-classic/kb/troubleshoot-gpu.html , especially Solution #4 to update to the latest GPU driver.

If you encounter GPU driver issues while using ML features in LrClassic/LrD/ACR, please try to update to the latest macOS version or if you are on a Windows machine, follow https://helpx.adobe.com/lightroom-classic/kb/troubleshoot-gpu.html to update your machine to the latest GPU driver and see if the problem resolves itself.

If the OS or the driver is not available or possible and the problem persists, then try the following workaround method as a last resort. The method provides a mechanism to allow LrDesktop/LrClassic/ACR customers to force the ML inference to always run on CPU instead of default. See details here https://helpx.adobe.com/camera-raw/kb/acr-gpu-faq.html#lens-blur.

It looks very promising, but in my case it seems to cause a GPU processing error, when I change the blur amount after the initial value.

cool, the masks are not perfect, sometimes edges of faces or stray hair got blurred.
we also need a way of adding back grain to the blurred parts to match the rest of the photo

In situation like blurred stray hair, The first thing I would try on the desktop, is to tweak the focal range control to extend the focus range a little bit to see if it helps; if not, try the brush based refinement tool.

The current workaround to add back grain is to create a mask and add local grain effects.

First impression: incredibly slow on M1 Max MBP 64GB RAM.

The first use of the feature after a fresh install would be slower because the macOS would need to do some optimization of the newly installed ML models. The subsequent use within the same app session and separate app sessions should be faster.

The same applies to Windows platform.

Just tried lens blur on an image of a sculpture that I captured last summer and it is amazing. My background was caotic but I was able to blur it sufficently enough to put the focus on the sculpture where it needed to be. What a wonderful tool!

At first look it all looks good. but bot Color Mixer and Lens Blur need a reset button.
