That's Affinity's tiled rendering being revealed by the rendering of a changed tile in two passes - a fast half resolution pass then a slower full resolution pass. You can prevent the flickering by switching to one-pass rendering in the Performance controls of the app's preferences/settings. Change the Retina Rendering from 'Automatic (Best)' to 'High Quality (Slowest)' and then relaunch the app. ('Low Quality (Fastest)' will also prevent the flickering but the document view will be rendered at half resolution.)

Affinity automatically considers colours to not match when their definitions are in differing colour models, therefore an RGB fill search will never find something that has an HSL fill, and vice versa.

in Serif's words: "by design"

The mask and selection options of Pen Tool are in Photo, but not in Designer. However, in Designer, you can give the Curve an opaque fill (any colour) then cmd-click the thumbnail of the Curve to get marching ants based on it. Edit: thanks to R C-R for pointing out that cmd-clicking the Curve needs to be done in Pixel Persona of Designer.

An adjustment layer applied to a picture frame on a Master page is a property of the picture frame, not its content, in the same way, applying a stroke or a fill to a picture frame on a Master page is a property of the picture frame... The stroke and fill can't be edited on the publication page without first detaching the master page, the same applies to an adjustment layer... You are still not understanding why there is a bug. The software correctly restricts access to an Adjustment that is a child of the Picture Frame itself - Edit Linked/Detached or opening the Master Page is required for accessing that Adjustment. Good so far. The bug is that the same restriction is wrongly applied to an Adjustment that is a child of the unrestricted Content object of the Picture Frame, not a child of the Picture Frame itself. The child of the unrestricted Content object should be as unrestricted as its parent, but it isn't.

Looks OK, but you should be explaining how you created/painted the Pixel objects in you document.

Yes, there is inconsistency and it is a bug. You have received flawed excuses/explanations and workarounds that should not be necessary. When a Content object (an Image, for example) of a Master Page's Picture Frame is accessible on a regular page without a requirement of invoking Edit Linked/Detached, a child (Adjustment or Mask, for example) of that Content object should be equally accessible, but instead the child wrongly has the same restricted accessibility as a non-Content child of the Master Page's Picture Frame. As you know, we can add a child to the Content object of a Master Page's Picture Frame when we work on a regular page without invoking Edit Linked/Detached, and immediately edit that child before it becomes deselected, which is sensible. It is nonsensical for that child of the Content object to later be uneditable without invoking Edit Linked/Detached. A bug.

Users have been coping with the name of Transform Panel without your suggested documentation, so they'll probably cope with the name of Point Transform Tool without that documentation.

Something was said in a beta thread not too long ago, I think.

Oh. I failed to read your mind. I would tell you, but you'll already know it.

Also translates (aka moves) objects. Translate, scale and rotate are transforms. The name of the tool seems appropriate.

It now works for several vector drawing/editing tools in addition to the raster painting tools: Pen Tool, Pencil Tool, Vector Brush Tool, Node Tool, Knife Tool, Corner Tool, probably others I've missed.

I agree. This is the 'Share your work' forum, not the 'Tutorials' forum, and the OP was merely showing their work and how they did it, rather than posing as a tutor. I also agree with Ash, that there are many misleadingly overcomplicated tutorials on the Web, but the OP was not presenting a tutorial and so the comments about poor tutorials would have been less potentially offensive if made elsewhere.

Easy method using Shape Builder Tool and Contour Tool: triquetra.mp4

No, the pasted objects are always together, with no option for replicating the parent Layers structure of the source objects.

An alternative method using Spiral Tool and not requiring Point Transform Tool: heptagram.mp4

To be considered:

I was hoping you would see my earlier post as it is now. I edited it only 2 minutes before you responded, so I understand why you were not aware of that. I could, but will not, provide details. Many regulars here will know why. No. End of my participation in this discussion.

[deleted because my initial comment would have led to a near endless argument that the forum doesn't need]

I think what's happening is the objects are staying grouped, but you have enabled the option which makes the individual objects be directly selectable as if ungrouped. In the Context Toolbar of Move Tool (and many other tools) is an Auto-select control; in its drop-down list, select "Default" instead of "Objects" to get the selection behaviour to which you are accustomed.

For the stroke of the spiral, use a 'vector brush' with texture that is a linear gradient. You might want to use a greyscale gradient and then apply a Gradient Map Adjustment to the spiral to colour it.

When you have at least 3 screenshots, a Live Stack Group with its mode set to Outlier should give the required result.

You're welcome!

Welcome to the Affinity forums The destructive Filters have never had a blend mode drop down, as far as I'm aware. I think you must have been using Live Filters when you previously saw the drop down.

I know, and that is exactly why my second sentence, which you quoted, suggested providing an option rather than forcing something on people.
