shift Q cursor clarity

[JohnSellers]

In the new GIMP 3.0.6 the shift Q hard round brush cursor is almost invisible.   What can I do to make it visible enough to see well?

Any fix that works would do fine, but also there is a refinement that would help a great deal.

I found that when separating transparent background from object, my visualizing the positional edge and of the perfectly round cursor of the right diameter increased my ability to judge the w/b painting clicks with treat imp;rovment.  

The flaw in the display is that the image I am working from is anti-aliased and the stair stepped brush perimeter is badly mismatched because the perimeter of the circle should be a smooth circle rather than a stair step approximation in order to exactly judge the placing of the paint.  In my current application of the paint, I have adjusted the parameters so that the exact tangent of the paint brush circle belongs exactly at the visualized edge conceptually defined by the anti-aliased pixels. 

If I had a smooth circular tagent parameter of the brush displayed when I work, I could place the brush so well that it would give me  an absolutely perfect result.

AFAIK the brushes used in the quickmask are the same as those used elsewhere, because you are just using the same paintbrush tool.

I hardly use the quickmask these days (especially to extract stuff) because layers masks work better.  Same principle, but if you later find that you made a small mistake, you can just amend the mask. And if you need a selection you can obtain it from the layer using Alpha to selection.

The only way to have an absolutely perfect result on anti-aliasing pixels in CGI is to paint in Color erase mode with the color of the background. Otherwise you either your edge pixels contain a bit of the former color (and you get a halo) or you have clipped too much. And this can be done easily with a proper selection. On photos edges are murkier and you can just aim for "adequate". And of course on photos things a lot murkier anyway, you can only aim for "looks good enough".

Might / might not work on your installation: Try changing the color / opacity of the mask.

   

Gimp 3.0.6 has a quickmask bug, it has been reported.
