AFAIK newer Intel graphics after core 6th gen CPUs are capable of OpenGL 4.x. Yes on my machine who has a 4th gen core i7 mobile processor, blender will nor run unless it uses nvidia video card.

This is because it previously relied on Blender Internal to triangulate the meshes, but that's missing now.

This is most likely to be an out of memory error. Unfortunately we are still searching for the best way to prevent this but this is out of our hands (the driver manages the resources).

I noticed the same with mesh hair (imported from DAZ studio), I ended up deleting all the faces that are not visible from the outside, then some more and finally I was able to get it to render. Without the hair mesh the freestyle render is so fast I barely notice it.

Indeed seems to be fixed, perhaps due to rB41cb5658803bf3b96f18e93c74c6af66ecdb1e83.
It seems this bug was fixed recently, at least on Linux.
Can someone confirm this?

Does it print anything suspicious if you run blender with --debug-gpu and render? (So it crashes)
i just checked with latest beta and for me freestyle only works, if I select a collection with no sub-collections.
don't know if this is a bug or meant to be, but I would prefer if it could render all sub-collections as freestyle too.

Does it only happen with eevee? Does it crash if you choose cycles instead?
Yep same thing

This is solved in 2.8, where freestyle uses the same triangulation as everywhere else in Blender.

Updating blender2.8 -> master in my local repo, and rebuilding, showed the problem is resolved. :)
In 2.80 (git built within the week (168a6a4bfc1)).
Linux (Debian stable).
Official Nvidia drivers. Geforce 970. Driver Version: 390.48

Excellent! You guys are too fast for me. :)
This was just fixed, your build is one day too old.

I have tried your file. If I set the collection to "Inclusive", neither cube will be freestyled. If I set it to exclusive, then both cubes will have freestyled edges. The issue I'm having is that I cannot make it so one cube is freestyled and the other not be.
Well, like I said: in the file I posted I cannot reproduce the issue, both inclusive/exclusive collection do work on my side, have you checked that file (if that works for you as well, it gives us a hint on how to proceed)
This bug occurs with both Eevee and cycles.
Cannot really reproduce here.

Still working on finding what is exactly the error number 2, and steps to reproduce it. I think it might have been solved already, and was related to a grease pencil object from an older version of 2.8.
I'll update/create a new bug report if I found something interesting !

Please follow our submission template and guidelines, also read these tips about bug reports, and make a complete, valid bug report, with required info, precise description of the issue (only ONE issue per report!), precise steps to reproduce it, small and simple .blend and/or other files to do so if needed, etc.

Thing is, i generally only run the unit tests when i either have to do a blender.org release or when i do library upgrades. having this many tests broken before I even start isn't great for me either, and makes quite a good case for running the unit-tests on the build-bot on a nightly basis. I'm happy to investigate most of the unit test issues reported (since most of them do appear to be platform specific) but i did think it was worth while to have a tracker ticket so we're aware that there's an issue and module owners of the problem area's can chime in and either fix the issue or give me a hint on where to look.
I confirm that, under linux, render is compliant to reference with 2.79b or master. So, it is a bug relative to OS.
Thing is, we have no idea whether that is supposed to be expected changes (and test should be updated), or if that’s actually valid bug… reporting that kind of issue months later is not reallyt helpfull either. :/

As I went to confirm that this bug got resolved I found that F12 rendering now doesn't work at all (Blender doesn't crash, but it freezes and must be forcibly closed), either with release or debug builds, and regardless of whether Freestyle is enabled or not. This only happens when EEVEE is the active Render engine.
Eeeeh ok, then I guess we can close as solved. :)

@Tamito Kajiyama (kjym3) mind checking on that one? thanks.

I've also noticed that the thing that seriously slows down my code is the OSD mesh creation. On the squirrel (17 106 quads) OSD creation takes 4.346086 sec while the rest of my modifier code takes 3.414331. I'll try to multi thread a part of my code. If that goes well then I might push the time down to around 1 sec for the non OSD creation stuff.

As of Blender 2.8 f08f6c1adec I'm not able to reproduce the above issue anymore (with a release build). Freestyle still doesn't get rendered correctly with EEVEE (F12 render shows a black screen), but I guess that's to be expected at this stage.

This time I even used a debug build, quickly obtaining a crash within 1-2 attempts of rendering the image with Freestyle enabled, as of e91bdb10e9c. Note that it says RX580 but it's actually an RX480 (there should be no difference OpenGL-wise; this is due to a GPU modification).
Could be a lot of things, but would suspect some OpenGL issue… Can you please run it with --debug-gpu option and attach as text file here any error printed out in the console (do not paste it directly in comment)? Thanks. Also maybe worth trying with -t 1 option (to run in single-thread mode).

It could be a GPU vendor-specific issue. What GPU are you using? I just tried again with the latest buildbot build, and it crashed on the first attempt, by the way.
Can't confirm on Windows 7
Rendered correctly with no crashes 15+ times.

A quick update. I've worked with the GSoC student YimingWu so see if my work would be useful with his LANPR solution (and it seems to be!).

Freestyle creates a new scene to render lines, which is not the same as the existing scene. In general Blender can have multiple scenes active at the same time.

Animated edge marks could be a partial solution (a workflow in this approach could be tedious and even not applicable in some cases though) -- see https://wiki.blender.org/index.php/User:Kjym3/DevFundProject/InterimReport for more information.
@Tamito Kajiyama (kjym3) Hey, by any chance can you take a look at this? @Zachary1234 (Zachary1234) was asking on IRC today if there is any chance that this could be fixed/improved/a way around the issue. Thanks.
