Confirmed here as well. It's failing during selection, not the drawing we see on screen.

I too think making uniforms for all parameters is the way to go, when editing or animating a material. Constant value nodes can be compiled for faster preview/playback when a material is not being edited. This is one area we can do better than the Unreal editor.

Thanks @Joshua Leung (aligorith), that debug dump has some useful info.

I'm working on this now! Should have a better solution in a few days.

Exact same issue on Mac + NVIDIA.

It should be fixed already, feel free to close as resolved after confirming.
FYI our new immediate mode handles this by recreating its internal VAO every time we start drawing to a different window (each window has its own GL context). Much simpler there because imm has only one VAO total, not one per batch, potentially thousands.
How about a more radical approach? Have one drawing context that all the windows use. The GPU already draws in sequence whether we have one context or many. The one drawing context has all VAOs so we don't have to manage anything ourselves. Adding yet another manager isn't the only solution.

I agree with @LazyDodo (LazyDodo) about removing "inline". Simplest solution & I've found static private functions to be as effective as inline. If we ever need public inline functions we can define this in gawain/common.h

The Geforce 8000 series are the oldest GPUs from NVIDIA that support OpenGL 3.3. I recently got an 8600 for compatibility testing. Windows 10 did not recognize it but I can try Windows 7 (otherwise the card might just be bad).

Excellent work @Sergey Sharybin (sergey)!

Thanks @Wo!262 (wo262) for the quick response! Hopefully Intel really fixed this between 4624 and 4627 and we just have to wait for the newer version to roll out.
I'll try to reproduce this issue on a debug build which should tell us more information. I only have a few NVIDIA cards though, none of the ones reported here...
@Wo!262 (wo262) what driver version? I would think HD 520 and 530 would have the same driver available.

Gawain's limit matches common hardware limits, that's why it's 16. This applies to active attributes in the shader. I talked with @Clément Foucault (fclem) before about aliases — these don't belong in VertexFormat, and the limit should not apply to them. VertexBuffer or Batch is a better place to track aliases... still need to figure out the details!

Please explain the difference between the new shader and GPU_SHADER_3D_POINT_UNIFORM_SIZE_UNIFORM_COLOR_OUTLINE_AA. Is it something that the rest of Blender (outside the 3D view) might want to use?

More results from Intel HD 520 + Windows 10.
Crashes inside Intel graphics driver while linking one of our shaders. This one!

I have some Windows + Intel systems here for testing.

Why remove modern and keep legacy? The other way makes more sense to me.
I'm testing Blender 2.78c on an AMD A10-7850, not seeing any issues. Tried different window draw methods, region overlap, nothing yet breaks it.

Good to see you @Antony Riakiotakis (psy-fi)! Thanks for digging into this & verifying that it does help.
Also try "OpenGL Occlusion Queries" in User Prefs | System | Selection.
It might be related to a change we made in 2.77 — always use VBOs to draw objects. @Small Sébastien (Conique2001) your graphics card has plenty of VRAM so should be able to handle large poly counts. So hmmm....

Thanks for the fix, I can't believe this hasn't caused problems before!
As of c8ab7d46566c4a65c6176cd2ebe27778512f7fef we use OpenGL 3.3 core profile on all platforms. We still have some implementation and cleanup work ahead, but this milestone is effectively done.

Bigger picture, I prefer function names mostly as they are. That's why I chose them! Some of the P453 changes are better though, so we can pick & choose.
Some notes on specifics, so we can use P453 as a base for discussion.

Fixed by unknown NVIDIA magic.
Just tested Blender 2.78c on latest Windows 10 (64-bit) and Geforce GTX 1050.

Edit mode edge drawing uses a different technique though. It can be updated to respect UI scale. Similar for round points with outlines.
I've gotten mixed results with wide lines on core profile.
For reference, here's the commit from the current (non draw manager) viewport.
Whaaaat? I thought we were removing all of this soon. How long until the depsgraph gives us post-modifier results?
Yes I'll take a look tomorrow, try to figure it out.
