Problem with second stroke of raster brushes in Affinity Designer, Pixel persona

[AlessioFB]

As you can see in the gif, if I start the second stroke right after the first one, then that stroke makes a "straight line" or a "v" shape, as if the line were jumping to the starting point for a frame.

My specs:
Designer 2.2.1
Windows 10
Processor:AMD Ryzen 7 3800XT 8-Core Processor, 3901 Mhz, 8 Core(s), 16 Logical Processor(s)
GPU: Nvidia GeForce RTX 3070
Monitor: Huion Kanva 24 (one of 4 monitors)

Please clarify: your topic title mentions both "vector brushes" and "pixel persona". One of those is probably wrong, as the pixel persona doesn't have vector brushes.

Thank you Walt,
I wrote "vector", but I meant "raster". I corrected the title. 🙏

Hi AlessioFB,

Could you check your task managers to look at running processes and try to spot any spikes when you draw. Does it also occur only the minimal displays running? What resolutions are you running them all at?

You could also try altering your performance preferences in edit > settings > performance to see if reducing the view quality/retina rendering setting/ disabling hardware acceleration have any affect on this issue.

Hi Lee, thank you for answering so fast.

Displays: I disconnected anything else, run only the graphic monitor, still having the same problem. (I run the rest of testing on a singly monitor). Usually I use: Huion 2.5k, another 2.5k, one 4k and one 1080.

Task Manager: no spikes at all. Everything flat and smooth. CPU and GPU barely notice that I am drawing.

Other software: no issues (I tested on Clip Studio Paint, to see if it was related to Huion driver or Windows).

Performance settings:
Retina quality: no difference.
Hardware Acceleration: no difference.

Renderer: I tried them all, no difference. (I wonder though why NVIDIA appears twice).

I could reinstall the NVIDIA drivers, if you think that could make any difference.

I have tested with new files and I noticed something interesting:
if I open a new file and I create a single raster layer, then the effect is very minimal. I can notice it only on the very end of few strokes.
But if I then add some other objects to the file, the effect starts happening.

I made two gifs for you, showing it with the same file, same resolution, same brush, with the only difference being the presence of few rectangles.


 

I hope this is helpful to find the culprit and a solution.

I also tried with "windows ink" as input method. And I tried making fast strokes with the mouse.
In both cases the effect was there. So I don't think it has anything to do specifically with the graphic table or the pen input.

A couple more questions, what's the resolution of the document and brush size, and can you recreate it with a mouse?

Lee

[AlessioFB]

I tried different documents. The newest gifs are from a new document.
I used the "iPad 12.9 Retina" preset. So 1366 x 1024 points. But it happens on documents of other resolutions too.


About the bruh size: I reproduced it consistently with all brushes of all sizes, from the simple "one pixel" to the heaviest and biggest texture brushes.

And here is a gif of mouse drawing on that same document, using a 4px round brush:

@Lee_T
in version 2.3.1 the problem persists.

Hi AlessioFB, 

Sorry for the delay in getting back to you, I've now been able to recreate this and we have it logged as a bug to look into. It seems it's to do with the the layers studio panel. Until there's a patch for this, a workaround is to hide the layers panel temporarily whilst you paint.

Wow, thank you!
Even though it's a workaround, it makes a world of difference! This finally allows me to use Affinity Desiner Pixel Persona to normally sketch before working with vectors.
Thanks 🙏

I am definitely trying this as well.
