Regarding this task, there are several points we must consider.

@Campbell Barton (campbellbarton) You are talking of free drawing an stroke or darwing a curve using primitive tool? it's not clear what you mean with "draw a curve", maybe you mean draw a "stroke".

@Charlie Jolly (charlie) Could you take a look?

This is related to the internal cache refresh flag. The problem is the cache is not refreshed in the second window and the onion is not visible. You can check in edit mode and you will see the onion is visible.
I need to find a way to solve it, but without impacting on the performance of the screen.

@j p (caricaturize) Did you test to parent the grease pencil object to empty, instead to parent the GP layer?

Maybe there was a name conflict when the materials for annotations was created... but not sure. We will wait until you are able to reproduce consistently to go deeper in the problem.

I cannot reproduce it. I have created a file in 2.79 and loaded and all is ok, then created a new file in 2.80, open it again and not problems.

@Charlie Jolly (charlie) could you take a look?

This is not a bug. The Hide operator of Grease Pencil is by layer, not by points of strokes. When you press H, you are hiding the whole layer. You can check this in the layers panel (the eye icon changed).

I'm going to reasign to @Campbell Barton (campbellbarton) because it looks a more general topbar issue.

This crash is a different issue. The object not visible is due a different reason...I'm thinking how to fix it.

I can convert to Curves. Did you try these options?

@William Reynish (billreynish) I have added the Shift+F to change opacity in Edit mode. Not sure if you want add in the Toolbar a new icon for this as you did for Thickness. Up to you.

Also, change uiTemplateList is something that can affect whole Blender UI, so you need the opinion of @Brecht Van Lommel (brecht), and maybe @Bastien Montagne (mont29) . Not sure it worth change this template only for this small UI problem... really, the user only need unpin ansd select new material, not a big deal.

I'm still not a big fan of using different formats for Material list when pinned, and this patch uses different UI layouts.

@Campbell Barton (campbellbarton) @William Reynish (billreynish) I have seen a problem with topbar (the same I have in grease pencil) for other objects.

The problem is the when delete an object, must back to Object mode as it's done with meshes.

@Charlie Jolly (charlie) could you take a look?

@matc (matc) It makes sense... I'm going to test with several files to see if nothing else is broken.

Try to run starting blender using this command: blender --factory-startup

• Don't check Node is NULL
• Fix style

If you set to 2D layer, you will have the transparency issue (this a know problem). You must set to 3D Space.

I cannot reproduce on Windows 10

Could you try to send us a crash log?

As the main problem of this task is solved, we can close it.

@Christopher Anderssarian (Christopher_Anderssarian) I understand your points, but we need at some point stop to add things and try to stabilize all. For sure there are a lot of things to fix, but we try to get something good enough... you know, the resources and time are limited. Anyway, it's my opinion only... I'm not part of BF.

IMHO, change annotations is not a primary task for 2.80. Maybe, we could close this task report because the problem is fixed now and open a new task with Annotation ToDos (not only the topbar and space issues).

I cannot reproduce it in Windows 10. Can you provide more details about your hardware.

@Christopher Anderssarian (Christopher_Anderssarian) We cannot use the Topbar because we have only one for screen. If you have a 3D view and a UV editor, you cannot detect what annotation datablock are you using.

What I want to do is keep all 2D editors equal. Today we have a "special" case for Image editor and the rest of 2D editors working differently. The logic, it's to set all 2D editor equal and remove the screen option. It's very weird that you draw an annotation and when you move/zoom the annotation does not move.

I have been looking at the code (I did not created this area) and I have seen there was an hacky special case for image editor when the image was NULL. The rest of 2D editors always set the annotation locked to canvas (affected by zoom) and never to Screen.

IMHO the best solution would be check if there is an image, and if empty, show a warning and cancel annotation.

@Christopher Anderssarian (Christopher_Anderssarian) Could you open a new report for the lock problem. It's better to have one bug by report.
