"Invisible" drawing on an artboard (Pixel Persona)


Recommended Posts

When I'm drawing on an artboard in Pixel Persona - the first lines are not visible.
They appear only after moving mouse cursor over them afterwards.
It seems that I have to "occupy" the area with those invisible lines first
to then be able to draw in it normally.
This problem does't occur on a regular documet with no artboards.

What tool are you "drawing" with?

Have you made the Artboard active by selecting it in the Layers panel or clicking on it before you start drawing?

Do you have any layers in the Artboard already, and if so which one is active when you try to draw? 

Can you capture and provide a video of this happening, so we can see exactly what you're doing?

(Your post feels more appropriate for the Questions section of the forum, rather than the Feedback section, by the way. But I would continue the discussion in this topic; a Moderator can move it to the other section if appropriate.)

I am using the Paint Brush on a pixel layer in this artboard.

On the attached video you can se that first two lines I draw are not visible. The appear only when I start to move the cursor above them afterwards. Only the third line appears normally (when the areas width and height is already occupied by first two lines).

This proble annoys me for quite while already in different documents, so I finally decided to write about it.

Thank you!

Can you activate and enlarge the navigatior panel? It shows a thumbnail of the drawing, and sometimes reveals rendering issues,

Then, check your brush (means: choose brush again).

In principle, there are some problem areas to distinguish:

  1. Brush not working (pixel layer does not “receive” brush strokes )
  2. rendering issues, layer data won’t get displayed (in time)

can you save file with history, and upload?
This allows to inspect the layer content (in Photo, allows more insight with info panel, Channels panel etc), and decide between 1 and 2.

Possible causes:

1. Brush settings, alpha, blend modes of other layers

2. Performance settings (Retina Rendering, View Mode, OpenCL, ..)

On iPad, I get similar issues.

rendering of brush strokes is severely delayed, often I need to adjust zoom to get the rendering.

Brushing over the same region again (like you do) could help, too.

On IPad, it is a category 2 issue ( rendering, not brush input).

Strongly assume a bug.

Hi All,

@NotMyFault As your case is with the iPad version if possible could you create a separate thread in the relevant forum section?

@only7yb If you could provide the files NotMyFault has requested we should be able to investigate this further with you :)

Thanks
C

Please tag me using @ in your reply so I can be sure to respond ASAP.

When you are using the following layer structure:

  • artboard1
    • pixel A
    • layer1
      • pixel B

You could use the same brush on pixel A and pixel B.

  • pixel A performs normal
  • pixel B is severely degraded / slow / stops rendering.

In the video, you can see the layer thumbnail updating correctly, but the main window does not update.

Designer:

Same issue in 1.10.4.1198 (retail) and 1.10.5.1227 (beta)

Same issue no matter if OpenCl on or off

Same issue with WARP.

If using a group layer instead of layer layer: same issue.

If using a white vector shape: no issue

Photo:

Rendering is ok in all variants.

 

Huston West Bridgford, you have a problem 😬

Hello everybody, here's another screen recording and the source file.
As far as I'm concerned it happens with any brush.


I'm using Affinity Designer 1.10.4.1198 on Windows 11 Home (on Windows 10 was the same)
on a Dell XPS 15 9560 laptop:
Intel(R) Core(TM) i7-7700HQ CPU @ 2.80GHz, 16.0 GB RAM
Intel HD Graphics 630 / 4095MB NVIDIA GeForce GTX 1050
