Invisible Node Links #70155

System Information
Operating system: Windows-7-6.1.7601-SP1 64 Bits
Graphics card: Gallium 0.4 on llvmpipe (LLVM 3.8, 256 bits) VMware, Inc. 3.3 (Core Profile) Mesa 11.2.0 (git-aa91c51)

Blender Version
Broken: version: 2.80 (sub 75), branch: master, commit date: 2019-07-29 14:47, hash: f6cb5f5449
Broken: blender-2.81-886adbbe49fc-windows64
Worked: blender-2.79.0-git.e045fe53f1b0-windows64

Short description of error
all links between nodes are invisible
nodes do not work on any version above 2.80
all links do what they should do, but node links are invisible regardless of the setting in "node editor"

Exact steps for others to reproduce the error
my system is incompatible with openGL33 required for blender 2.80, so i use dlls to be able to run on openGL32, it may be because of this incompatibility with opemGL32 that the nodes are invisible, but i still think it can be fixed, because the only thing what goes wrong with Blender2.8 on my system is the problem with the nodes, it works perfectly in its version 2.79

thanks for the time ^-^

OpenGL in Blender 2.7x has pretty much nothing in common with the one we use in 2.8x, there is not much that we can do here really. I’d say you are already very lucky that Blender 2.8x does start on such set-up, it’s really not designed for that, and we cannot support it in any active way. Thanks for the report anyway.

@jfkalandor what gpu do you have-filtering?
the mesa drivers are a lot old ...
start updating these
https://github.com/pal1000/mesa-dist-win/releases
you will surely find interesting positive surprises here ;)

@mont29 I did some tests and it works fine (slow)
https://github.com/pal1000/mesa-dist-win/releases

always better than crashing blender on gpu not supported ...
the compressed mscv package weighs only 16 mb and is accelerated by llvm 9. .. I am of the opinion that you should include this package in blender, and let blender start with these dll instead of crashing blender on non supported gpu

here is a cpu rendering with eevee ...

OpenGL:
============================================

renderer:	'llvmpipe (LLVM 8.0, 256 bits)'
vendor:		'VMware, Inc.'
version:	'3.3 (Core Profile) Mesa 19.1.7 (git-f632aac938)'

Screenshot (183).png
in reality it could start mesa via cpu acceleration, but I didn't get any results, something went wrong or I missed a few pieces on the street ..

maybe you are more luky

@nokipaike Thanks, we are aware of those software OpenGL emulation solutions, but the performances are really terrible then, those are not practical solutions besides debugging tools… Not worth spending time to actually package them with blender, handle their installation, etc.

I understand, but OpenSWR it's not so slow https://blender.stackexchange.com/questions/140842/can-you-render-using-the-cpu-with-eevee

actually 'm rendering "with" CPU ;=; //Intel HD Graphics/+/Onboard memory
i'm stuck in the updating mesa thing
'm just a newbie adventuring with python and blender(BGE)

@jfkalandor as you noticed from the posts I wrote later, I did tests myself, and "the same updated dll mesa" that I linked you make blender run well
