@cosquer (jakez27) thanks for the report, I have a few questions for you:

This wasn't happening in 2.80. It may or may not be related to the file browser changes, but odds are, they are.
Release mode is fine so the assert may be a false alarm.

Yet to confirm but it is a likely issue. We are about to do some changes in this area (D4416) so I will wait after that is merged to look at this.

The light strike doesn't work even if you manually advance the frames (as oppose to playback).

Thanks but we can't use private files in your debugging process. Another round of questions:

Thanks for the report. I can confirm this but I need some more information from you.

I cannot reproduce this with either the latest stable, current development version or the one you mentioned originally.

@Sergey Sharybin (sergey) want to add this to the depsgraph bug fix guide? How to proceed for race conditions in the depsgraph evaluation?

Thanks for the report, the issue reported here is a request for modified/improved behavior and not a bug in current behavior. Closing this report since we restrict user reports to bugs/errors.

Thanks for the report, the issue reported here is a request for modified/improved behavior and not a bug in current behavior. FBX development is on hold, we are only reviewing patches that we receive. So closing this report since we restrict user reports to bugs/errors.

Thanks for the reply @Richard Antalik (ISS).

Confirmed. It should be a straightforward fix, and in a way it is the same solution for both:

@Michael P. (forest-house) Can you test with the official 2.80 release (blender.org/download) and also a night build (builder.blender.org) to see if the problem persists?

Can you tell me how the error address can be used to diagnose a problem?

While trying this with a debug Blender I ran once into a undo issue:

Thanks for the report. I don't get the crash, but EEVEE DoF is very resource intensive, and things get more demanding the smaller the focus distance, so the crash seems like to come from your system running out of video memory or similar.

@Richard Antalik (ISS) can you take a look at this? Not the regression from 2.76 to 2.78. But the difference between the default VSE settings in 2.80 and 2.79 that makes a video "by default" to play slower in 2.80. It must be one of the default settings that are different.
Maybe the reporter (@Félix (Miadim)) can help nailing this down as well? You should be able to do it without any coding.

(see BLO_update_defaults_startup_blend and the blo_is_builtin_template call to see how to find if you are in the 2D Animation template)

@Antonio Vazquez (antoniov) is this something small/simple enough that could be done in the versioning_defaults.c file directly?

@William Reynish (billreynish) what is not clear:

• What do we expect when copy/paste in outliner?

My suggestion: We copy the collection and add it inside the current selected collection?

@Nathan Craddock (Zachman) is this something you would be interested on?
@William Reynish (billreynish) do we have a clear design on what to do here? It seems that copy/paste for collections is undefined everywhere (e.g., in the viewport is simply paste the objects)

Also please go to File → Defaults → Load Factory Settings and then load your file to see if you still can reproduce this issue.

Thanks for the report. We need a file where things happen. Ideally before the issue is about to happen (as in, when you only need to move the bones around to see the issue).

I cannot reproduce this with either the latest stable or current development versions of Blender.

Thanks for the report. It seems that you are "mistaking" the concepts of Save As and Save Copy. The tool is working as intended. What you expect to happen would be "Save Copy".

Please add a sample .blend as per the the report template instructions.

Please go to File → Defaults → Load Factory Settings and then load your file to see if you still can reproduce this issue (so animation nodes doesn't interfere with the crash).

This actually seems a running condition issue, likely on depsgraph end.

BLI_assert failed: //source/blender/blenkernel/intern/customdata.c:2099, CustomData_get_active_layer_index(), at 'customdata_typemap_is_valid(data)'
Full backtrace: P1102

Any other tool?

@Sam Mousa (Mrqozy) please keep the discussions here strictly on topic. This is a place for code review of this patch, anything else just adds noise to an already large patch discussion.

• From review rename: lock -> local

Can you try changing the property directly:
bpy.context.scene.view_layers['View Layer'].cycles.use_pass_crypto_object = True

@David Wende (davidwende) Please try with File → Defaults → Load Factory Settings and then load your file (so no Animation Node) to see if you still can reproduce this issue.

Thanks for the report. Unfortunately the scenario you describe is too complex for us to track down without spending an amount of time we cannot afford at the moment.

It sounds about right, if you tested and the UI works for both Cycles and Blender, go ahead

Alright, I managed to reproduce with official 2.80 but not with a recent release build. Closing it for now. If the problem persist with a build from builder.blender.org please let us know and we can re-open it.

@Gant (Gant_Valgant) we need to know the exact Blender you are testing. You can get it in the Python Console inside Blender with: bpy.app.build_hash

Assuming it is a dupli of T69785. We can reopen if user can still reproduce in latest Blender.

@Zachary (AFWS) :

1. Can you reproduce from your attached file?
2. Can you reproduce it from scratch (add objects, join them, ...)?

Please attach a sample file with a problematic font and a screenshot with the expected behaviour?

I cannot reproduce, please attach a file right before you start the transform step.
Does it crash as soon as you start to move?

Implement resetting on file load

Small cleanup, removing commented out code
