P: Brush Lag in ACR Mask

I went away on hoilday for a few weeks, and I am back editing. I noticed that only when I am in Camera Raw Filter and I am trying to use the brush to remove or add to a mask or even to use it to create a mask it is really lagging.
It is only in Masks when I have this issue. If I am just painting on a photo or doing anything else I have no problems.

PS 27.2
CamRaw 18.1.1.2422

Mac M2 Max

macOS

I'm having pretty much the same issue, but mainly when i use the 'select subject' mask in camera raw. It obliterates PS. Everything starts to lag, and if i'm lucky i'm able to click "done" and get my changes saved, but sometimes i lose a lot of work.

Hi @JA.Photos, thanks for giving this a try and sharing your results.
We will be looking into this issue in more detail. I’ve moved the thread over to the Bugs board so it gets proper visibility. Really appreciate you reporting it.

Hi @JASON22038575n9qp, thanks so much for sharing the recording and happy New Year to you too!
I did a bit of digging and found some previous reports from Mac users having similar issues with Wacom tablets in Camera Raw:

I’ll check with the team to see if this is currently being worked on. In the meantime, a few users mentioned that turning off GPU acceleration in Photoshop preferences helped. Could you give that a try and let me know if it makes a difference on your end?
Thanks!

@Aleke Ok so i turned the GPU in peferences under Performance. In my honest opion I think it is lagging even more with that off. But I could be worng, it does seem like the lag time is greater with it off than with it on. In anycase that did not help at all.

Hi @JASON22038575n9qp, welcome to the community!
Could you check Activity Monitor to see what’s using CPU and RAM? If you notice a non-essential process taking up a lot of resources without a clear reason, stopping it might help. You can also try these general tips to improve Photoshop performance:

If that doesn’t solve it, please share your System Info from Photoshop. You’ll find it under Help > System Info. Just copy it into a text file and attach it here, or share via Google Drive, WeTransfer, or another file-sharing service.
Thanks so much!

@Aleke

still no luck. it is odd, that i have no issues in PS with the brush only Camera Raw in Masking. I also am using a Wacom Cintque Pro 24PT, but like I said, no issues with PS bush using the Pen, only Camera Raw masking. below is the copy paste thing

@Aleke also it is only in camera raw.....I just went in LRC and it works 100% no issues....so I am wondering if it is a camera raw problem?
