Hi I'm experienced photoshop user but I'm having a serious troubleshoot with the soft brushes since 1 week.
As seen in the following image my default soft brushes making halos and bandings.They must be transparent but they're producing sharp edges and acting like they have glow effect.This problem only occurs with dark backgrounds like black color.
I tried to reset all my brush tool settings and photoshop preferences. I Updated my graphic and wacom tablet drivers and also my windows 10.

I canged my image mode 8 bit to 16 bit but nothing is changed.
I uninstalled photoshop and reinstalled it but the problem still continues.
My color profile is default sRGB IEC61966-2.1 and my monitor is calibrated.

How can I solve this problem.I can not paint with soft brushes without this halo/glow like effect.

I fail to discern the issue in the screenshot. 

Could you please post a screenshot taken at View > 100% with the pertinent Panels (Toolbar, Layers, Brush Settings, Options Bar, …) visible?

I fail to perceive the issue in the screenshot. 

Does going to 16bit and checking »Noise« alleviate it?

I forgot to mention that, my brush panel opacity and flow settings doesn't changed the situation.Also smoothing.

Normally these brush edges must be seen on a black surface like feather applied.But they look like glow effect halo.

Like I said I fail to see the issue in your screenshot. 

Could you try changing the monitor profile to sRGB on the OS side (just for testing whether the monitor profile might be involved)?

Going 16 bit image mode is fairly changed but it doesn't solve my problem.

If you're working with 16 bit data, any banding you see is in your display system.

 

Banding is always a result of insufficient bit depth. The display pipeline from video card to monitor works at 8 bit depth, and that's where the banding happens. There's only 256 discrete steps from black to white per channel.

 

The most annoying aspect of banding is that it's cumulative. There are several places in the signal path where those 256 values get slightly shifted. They all go on top of each other, and so the final result may be highly irregular color banding. A common culprit is calibration tables in the video card (which is why a hardware calibrated monitor, i.e. one where all adjustments are performed internally in the monitor's own processor, in high bit depth, is a huge advantage) . 

 

The only way to avoid it completely is to use a 10-bit capable monitor and video card. Short of that, the common workaround is to add a little bit of noise or dithering. Not much, just enough to break up the banding.

Hi, did you try a most recent version, like  22.5,?

Do you have an image on how it is supposed to look? 

Could you post a screenshot of your color settings?
