LAG when ALT-Clicking to sample - Clone Stamp and Healing Brush

Hello,
Using the healing brush and the clone stamp tool with "show overlay" activated introduces a small but inconsistent lag when pressing the alt key to change the sample.

With "show overlay" deactivated, this lag is not there and the change from brush to sampler is instantaneous.



For professionals who work fast this is very annoying. Alt-clicking sometimes result in correct sampling, but other times it results in a small unintended brush stroke followed by a couple of undos, to then start again.

Photoshop CC 22.0.1
Windows 10
Intuos Pro L (driver 6.3.41-1)

i9-9900K
32Gb RAM
RTX 2080ti (latest drivers)

Thanks

I am having the same issue. When I go full screen with no toolbars the issue with clone stamp and healing brush stops. I am not wanting to work in full screen, but that is the only solution I have found.

Issue continues in 22.1
Disabling "show overlay" is still the only practical solution to eliminate sampling lag with the cloning tool and healing brish.

Sadly even in my case that only partially fixes the issue. This occurs on the mixer brush as well and liquify. It seems like anything that is more GPU intenstive it just lags. Even when you're working in a small radius.

In that case the problem may be a different one. Try using PSAssistant to disable the alt key triggering the application menus.

Scroll down to find the download button.
Tell the program the location of the photoshop executable and keep the program running along with photoshop. Make sure you activate the "disable alt menu" option in the hotkey section.

Wow, I think that actually worked. I did notice that VirusTotal flags the application, but sadly it appears it does work. The lag was being caused by the Alt menu pulling.

It's probably a false positve beacuse the way that program works. A lot of people use it. I use it. It solves 50% of the alt-click dilemma.

NEW FINDING
So I confirm that the issue persists in 22.1.0 version. Disabling "show overlay" is still the only workaround.
Now I have found that this problem only appears at high zoom levels. If you zoom out, alt clicking shows no lag.
