P: Healing and Spot Healing Brush Lag

Hi Adam, I did this about an hour ago (Reset Prefs on Quit) and so far so good

This is happening to me too, I've called tech support twice, I hope Adobe comes up with a solution quick because it's costing many of us time and money for this insane lag, restarting PS over and over again is a lame option and not realistic. Tech support told me to reset brush settings to default but this is a pain too that doesn't always work. I use a Wacom Cintiq 13 touch tablet but it does the lag even without the tablet.

I'm about to go back to 2017 version because this one should never have been released with these glitches. Next time they should have full time professional retouchers and artist use the products before they release them. It would have been discovered in minutes...

16bit, RGB, 25MPix, mouse.
Lag starting after around 25 clicks (+3000Mb of RAM / working set).
GPU peak to 25% during each lag
CPU peak to 30% during each lag

have the exact same situation on Win10 with Intell 8core, 32gb ram and nvidia 1060 6gb. The bug is in the (Spot) Healing Brush tool, the Patch tool works perfectly like with PS18.

Definitely helps to have smoothing turned off i.e. at 0 but I found I have to set the brush smoothing to zero and then close Ps and reopen. Just changing the smoothing to zero on the brush and going back to the healing brush whilst still in an image had no effect.

By the way has anyone else lost the ability to use the space bar to get the hand tool to quickly move the document?

.dng file (from Canon 5D3) opened from Lightroom i.e. no layers. I add a single transparent new layer above to do healing. The first heals are ok for a short while then it just gets very slow as reported by others. Have to close and re launch Ps every few minutes to get the speed back. It used to be as close as possible to real time but now it's worse than Lightroom. Using Wacom on MacOs Sierra

how to disable brush smoothing?

Turned smoothing off and restarted and it definitely helped. Still a tiny lag much more than the 2017 version though but definitely better with smoothing off.

Still have a problem on my Win10 PC (last update,16GB RAM), even when a smoothing is off. I have to restart PS, then everything goes fine for a hour or so.....then horrible healing brush lag appears again.... 😞 
Everything worked fine in PS 2017 

doesn't work for me......still have a lag on healing brush, even when I disable a smoothing option in brush window (win10,16GB)
