(Fixed - Locked thread) Mixer Brush not working properly (build: 23.4.1)

I've got the same issue.

I want to use the mixer brush without a color, but on every first stroke it sets the foreground color as its own color and make a mess. Seems to happen every time I open a new document.

@KS-JMP Yep, have a Dev looking at this bug right now. Thanks for the video.

Sorry this took awhile for me to make. But here is a video that demonstrates the problem.

Scenario: Each time the mixer brush is newly selected from Tool Presets, it will cause problems on first stroke. Undo, then second stroke yields a different (normal) result. Selecting a new mixer brush preset yet again results in the same behaviour.

more update more problems come out!

press b b b but the brush dont want to come out!

and when brushing on the layer mask, there will brighter the image!

Thank you Chad. The issue is reproducible if you create a tool preset. Then select the mixer brush through that tool preset instead of the left panel. That will cause the problem to occur.

UPD: please merge with this thread: Mixer Brush not working properly (build: 23.4.1)

The problem appeared in the latest update (23.4.1). Widows 11

The essence of the problem is that when opening a new document and activating the Mixer brush tool preset, the first stroke is not always, but often black. As if color overlay is enabled:

But it is turned off both in the tool settings and in the preset settings:

All subsequent strokes in the same document do not have this effect and work correctly until the end of the work with the document (without any additional actions, it is enough to draw the brush one more time). On the next document, everything is repeated again. Reset photoshop settings, reset tools settings does not help. Deactivate native canvas and disabling graphics card acceleration don't help (either together or separately)

Problem only when working with preset. If you just select a tool on the panel and adjust it, then everything is fine.

I can't find a definitive way to reproduce this. The problem comes and goes. In the video, I open a 56.8 mb PSD file with one background layer, 695x463 mm 300 dpi from the disk, gaussian blur it (maybe this is important), then activate the preset and try to make a stroke. I noticed that the problem does not appear on newly created documents (or it appears extremely rarely). Also, the problem does not appear if you re-open the document on which it manifested itself.

@ジョルダーノ Thank you!  I'm able to reproduce the issue and will have assigned the bug to a Dev to fix. 

@Chad Rolfs no, all my presets have that option not selected:

@Chad Rolfs  no, in none of my presets: all have that option not selected
