Drawing update glitches with pixel layer in a group

[Rob W]

When a pixel layer is included in a group the drawing on the screen is glitchy (see attached screen capture).

Steps in screen capture:

1. Drawing with a simple brush on a pixel layer included in a group (glitchy)
2. Undo drawing and move pixel layer out of group
3. Draw in pixel layer outside group (OK)
4. Undo and move pixel layer into group
5. Drawing is glitchy.

I probably should have included: MacOS Ventura 13.1 & Affinity Photo 2.0.3

There are known issues with brushwork on pixel layers inside vector layers, and I think being in a group might count. At any rate, your video seems to have the same behavior as reported elsewhere, since V1 and still unfixed.

Thanks for the insight, Walt. I'd never encountered it before. It seems quite the limitation on using groups.

I am a bit surprised that being in a group would cause it, myself, but your symptoms seem to match what I've seen in the other reports.

If you were to Ungroup the pixel layer and that resolved it, that would confirm it's the same issue, I think.

The problem originally surfaced on my iMac Pro (intel) but it also happens on my MacBook Pro with M1 Pro chip. It seems to occur if (all?) the pixel layers in the group have transparency.

From limited testing, if I draw onto a pixel layer within a group (glitchy), then move it out of the group (now with some non-transparent pixels), then move it back into the group it draws just fine. (Only tested on my laptop.)

I think this might explain why I've not encountered it before—previously I would group layers I'd already drawn but in my attempt to be more organised, I've begun to group layers before drawing on them. So much for being organised!

I cannot confirm this behavior with Monterey 12.6.2. With this it works as it should (APhoto 2.0.3)

I've bumped the bug report again. Sorry about this
