P: Healing and Spot Healing Brush Lag

For me it has nothing to do with dust and scratch. I haven't noticed a pattern, but it will happen shortly into the first image I start work on after opening the program

I had this issue before the update, but only on files of 2GB+, many layers, 16-bit, RGB.
Now having it on files of ~117mb, 1 layer, 16-bit, RGB.
Does it with wacom tablet, slightly quicker with (Logitech) mouse. Haven't tried a larger file yet.
Win 7, 16GB RAM, letting PS use 12GB. Loads of scratch disk space.

oh and changing colour temperature also take longer than the last version.

Same issue here and it's getting reallllyyy irritating. You click heal and then...nothing happens for like 1-2 seconds.

So how long has a retouching session been before this happens, and is it always after the dust&scratches filter? I tried it out on an old scan using D&S to remove just the smallest bits of dust, then spent another 15 minutes rapidly going over the entire image with the Spot Healing brush, and I had one incident where it "connected the dots," which it sometimes does, but other than that, it never lagged at all and I never slowed down. So does it take going through a few images like that to make it become a problem?

I am having the same exact issue. Reseting PS fixes it. But, it ALWAYS crops up again AFTER I run the dust/scratches filter. That seems to set it off for me.

I tested this and it gave the same results as restarting the program... works for a bit then goes downhill

Medium sized images—as far as pixel dimensions, Mac El Capitan on an old Mac Pro with Wacom Intuos 4. No lag. Brush sizes over 300 px might take just over a second. Brushes 1000 px + can take up to 5 seconds with use all layers depending on detail, or lack thereof, to pull from, but more typically are taking about 3 seconds. Spot Healing or Healing the same. I did check on the driver—I'd updated my Wacom driver not long ago when I'd had a problem, but saw that now I'm not on the latest driver. I'm on 6.3.24.1 and current is 6.3.25.2. 

So with my setup, I'm just not seeing this.  Oh, should add, I'm using both 8bit and 16 bit images all the time.
