P: When I am brushin on a mask, the option to switch between black and white stops working and I can only brush in or out.

When I am brushing in or out on a masked layer, after one or two switches between black and white, it stops switching and I can only brush in or out. It makes it impossible to use masking on my layers.  It doesn’t happen every time, but probably about 75% of the time.

    Worked again after an update, broken again after the next update… 

    Now when I have two random swatch colors on a normal layer, then switch to a mask, instead of automatically changing the swatches to standard black and white, it converts the previous random colors into their grayscale equivalents.

    Also experiencing the bug again where the colors remain instead of black / white / grayscale after selecting the mask.

    Seems like masking is completely broken since V28.0.1. It is unusable now.

    I’m also having this issue. Black / White not appearing by default when selecting a layer mask (instead the default swatch colors remain).

    Also, I’m having either black or white be “stuck” so that I can only remove or add to a mask (regardless of which color is currently active).

    Cannot paint on a mask. Also, when I am in quick mask mode black and white bushes act as a black brush.

    Happens on Windows 10 Pro v22H2 19045.7807 as well (I know I need to switch to 11). Steps to reproduce are rather inconsistent. Usually happens upon multiple switches back and forth between foreground/background color. Color picker window will not usually fix this.

    Edit: See other post here for additional info

    On the layer mask thumbnail, painting black (set at 100% opacity and flow, and with pure black and white) is not removing the portion of the mask, it paints it in, but does not remove

    I am experiencing the same problem. Photoshop Beta v28.0.1. It seems to have started on this update, so my plan is to revert to a previous version until it can be fixed

    To add to the original complaint, you can sometimes get the problem to correct itself, however as I experience the issue it becomes harder and harder to fix on its own. First, I switched to a different tool (adjustment brush tool) and upon switching back, that fixed it. Then the next time the problem happened, this fix did not work. Switching to the pencil fixed it. Then, then next time this happened, neither the adjustment brush or pencil fixed this. It’s almost as if it’s a virus affecting the tools

    The issue will occasionally persist through saving and reloading the file in the same open instance of Photoshop. It can also persist upon closing and reopening the program. The problem occurs when switching between black and white in the raster mask layer (I use the X keyboard shortcut to swap foreground and background colors). It’s happening very frequently for me and masking is unfortunately an incredibly important part of my job so it’s affecting quite a bit of my workflow

    The same. No matter black or white selected, both draw white on the mask mode. 
    And same solution - is to switch to the brush tool. And If the bug appears on Brush tool - then switch to Eraser.
