Hallo @Dan C, vielen herzlichen Dank für die Mühe, die du dir gemacht hast. Das erklärt natürlich alles. Nachmal ist man selbst so sehr auf etwas fokussiert, dass man die einfachen Dinge (Fehler) übersieht.
Somit können wir das Thema als gelöst abhaken.

Gern geschehen, danke, dass du das für mich hochgeladen hast!
Ihre Pixelebene in diesem Dokument ist auf 9 % Deckkraft eingestellt, was bedeutet, dass sie im Anschnittbereich der Datei sichtbar ist, aber vor dem hell-/dunkelgrauen Hintergrund der Benutzeroberfläche der Affinity-App etwas schwer zu erkennen ist.
Der folgende Screenshot zeigt mithilfe von Farbwerten den feinen Unterschied zwischen dem Anschnittbereich, in den sich das Bild erstreckt, und dem Pasteboard, in dem das Bild ausgeblendet ist -

Der weiße Rand in diesem Screenshot ist einfach der Rand der Leinwand, der konstruktionsbedingt nicht in den Anschnittbereich überläuft.
Ich vermute, dass dies auch der Grund dafür ist, dass Sie in einer neuen Datei nicht dasselbe Problem sehen, da die Pixelebene wahrscheinlich auf 100 % Deckkraft eingestellt wäre.
Ich hoffe, das klärt die Sache  

Oh, danke dir vielmals, gerade getestet, bin am Mac, da ist es die Option-Taste.
Alles wieder gut 🫠

Thank you @walt.farrell, I didn't know serif wasn't part of the discussion.
Yes, I found it after I posted here, that this request will be available in the next versions. Good news for me 

Quick tutorial on how to make a watermark and a few ways to save/store them to be imported quickly 

@dubtronics
I just created a handy Layers Guide to help navigate some of the eccentricities of Layers and Masks.
I posted it in the Tutorial Forum here:
 
Hopefully it can help you attain mastery of wrangling layers.
 

Thank you, yes, this short explanation did help me very much.

No, it is not that difficult …  :)
 
Basically, you can think of rasterising as a process of taking information from a certain source and transform it into pixel information. The outcome of a rasterising process will always be a pixel layer. And the basic parameters for calculating the pixel information are taken from your document and the respective source. There are at least four main areas of applying the rasterising process:
Placed objects Vector objects Layers with modifiers like masks, effects, (live) filters, or (live) adjustments Pixel layers Let me quickly describe these applications one after another:
Whenever you place an object in a document, it will show up as an image object there. The placed object will retain most of its properties, such as the native resolution, while some of its properties get changed, such as the colour profile. Rasterising an image object will turn this object into a pixel layer, thereby stripping the original properties from the object and rendering it at its current size into the document.​ Whenever you rasterise a vector object, such as a curve or a dynamic shape, the vector object will be rendered into your document as a pixel layer. Since the vector information will be transformed into pixel information, you will loose the editability that is typical for vector objects, but you will gain all the editing options that are typical for pixel objects. For example, you can make pixel selections now or use the eraser on your new layer. Now suppose you nested modifiers like masks, effects, (live) filters or (live) adjustments to a layer of any type. Then these modifiers will appear as children of your layer in the layers list. When you rasterise the layer, the information that is contributed to the layer by the modifiers will be merged with the information provided by the layer itself, and the outcome will be once again a pixel layer. Rasterising a layer with a lot of modifiers applied will free system resources, since these effects don’t have to be calculated anymore. But you will loose the option of editing the parameters of the applied modifiers. Finally, suppose you have a pixel layer that overlaps the document boundaries. By rasterising the pixel layer, you will in effect trim that layer down to the document size. The overlapping areas will be lost. Furthermore you must be aware that some other processes require the rasterising of layers beforehand, like the application of certain effects. Hope these explanations make sense, and help to clarify the issues a bit.
 
Cheers, Alex  :)

You're welcome, @PixelNik.

Just the circular red logo on a transparent background (attached logo is a PNG with transparency) ...
circle_on_trans_background.png.zip circle_on_trans_background.afdesign
Convert the image layer to pixel (raster) via the layer commands, then via the Pixel persona make a circular selection more exact than mine here and copy over to doc with a transparent background. Save the whole as a PNG to keep the transparency outside of the circle. - That just in case you want to have your circular logo stand alone. Otherwise for usage inside your actual document follow Carls advice.

Hi PixelNik,
Welcome to Affinity Forums :)
No, there isn't a trial yet, but i believe it will be available soon. I will check this for you.
