System Information
Operating system: macOS Monterey 12.7
Graphics card: Intel HD Graphics 530 / Radeon Pro 450 (Metal is enabled by default)

Blender Version
Broken: All Blender 4.1 Alpha daily builds
Worked: Never (at least on macOS)

Short description of error
After I enable Experimental > Grease Pencil 3.0, restart Blender and try adding any Grease Pencil object, nothing shows up, no Stroke, no Suzanne, no Empty. When I switch to Draw mode, I can only see the cursor moving but nothing gets drawn.

Exact steps for others to reproduce the error
I guess the Grease Pencil 3.0 development is being done exclusively on Windows and no one has yet tested it on macOS.

Thank you for any feedback as to when GPv3 would be tackled to work on macOS.

It doesn't work on Linux well as well, and last time I checked it didn't work on Windows as well. @filedescriptor do you need reports like this to track issues at this point?

@iss, @filedescriptor, Grease Pencil 3.0 being arguably one of the most anticipated features of the upcoming 4.1 release, some transparency about its current status (what's working and what's not) would be greatly appreciated. Thank you.

@antonheg The project is still very much WIP. If you want to know what is already working I recommend looking at the bi-weekly meeting reports here: https://devtalk.blender.org/search?q=Grease%20Pencil%20%23meetings

@iss Yes, I will add this report to the list of open bug reports on the grease pencil workboard.

Can confirm on macOS Sonoma running on MacStudio M2.

Actually, I don't think GPv3 is broken on MacOS: I just reset my startup scene to factory settings, and now it seems to be working fine. The various UI elements that weren't showing up in Draw Mode are all there now, and most importantly I can draw. See attached screenshot.

~~So I'm betting that the real issue here is using a custom startup file saved from an older version of blender, which is a completely different problem and probably not OS-specific at all.~~

Edit: Sorry, this turned out not to be true. See my follow-up comment below.

@Douglas-Paul, from you screenshot, it seems like you're still using the legacy Grease Pencil. Can you please enable Experimental > Grease Pencil 3.0, and restart Blender first?

@antonheg Yeah, sorry, it turns out I got a bit ahead of myself: I was so excited when GP worked after a factory reset that I completely forgot that the factory reset disabled GPv3 in the experimental options. 🤦 So, apologies for the churn and the false information.

I do have a real update, though, that might actually be useful info: Some aspects of GPv3 do seem to work if I add more than one Grease Pencil object to my scene. To be specific:

If I add a GP Suzanne or Stroke to my scene, I can see its origin in the viewport but not the strokes or fills. And if I enter Draw Mode on this object, none of the strokes I add are visible. Basically nothing for this GP appears to get rendered in the viewport no matter what I do, but in the Outliner I can see the data exists.
If I add a second GP object to my scene, then I can see its strokes & fills, and I can also see the strokes I as I add them in Draw Mode.
Any additional GP objects I add also seem to work fine.
If I then remove the first GP object I added, then the second GP object added becomes invisible, and and any additional GP objects start displaying incorrectly.

For me, I think this gives me enough of a workaround that I can create the test scene I need for #102285.

I wonder if this issue is still present with the recent changes in the rendering? There were some changes to how we merge the depth buffer with the scene buffer, so maybe that fixed it?

@filedescriptor No, sorry, I just pulled the latest on main and I'm still seeing the same issues.

From what I could tell in the time I spent fruitlessly investigating this a few weeks ago, the Metal shader is muddling up the material indexes. Here's what I see if I simply add a Stroke and then a Suzanne. Note how the Suzanne is being rendered with the Stroke object's materials, and the Stroke object isn't visible at all.

It seems to me like the sort of issue that might require the attention of a Metal expert like Michael Parkin-White.
