Switching to opengl3_angle rendering backend fails to open projects in compatibility mode

[WagnerGFX]

Godot version

v4.2.beta.custom_build [b662d23]

System information

Windows 10.0.19045 - GLES3 (Compatibility) - dedicated NVIDIA GeForce GTX 1650 (NVIDIA; 31.0.15.4592) - Intel(R) Core(TM) i7-2600K CPU @ 3.40GHz (8 Threads)

Issue description

This has been happening on the latest artifact builds, but not on 4.2-beta3

The drivers are updated and the PC rebooted.
The build console seems to recognize OpenGL API on 3.3.0 and my GPU can run up to 4.6

I was planning to wait for beta4, as this could be due to different build settings, but decided to open the issue anyway, in case it's important. 👀

Steps to reproduce

The MRP's contents are of little importance. Instead, it's a project in compatibility rendering using opengl3_angle for Windows.

Official builds use statically linked ANGLE, CI build does not, so a compatible libEGL.dll and libGLESv2.dll should be placed in the executable folder for it to work. You can build ANGLE from source or extract required dlls from the minimal CEF distribution - https://cef-builds.spotifycdn.com/index.html

Oh. . . I was right on thinking it was about the build, I just didn't know how.
Now it's working normally, thank you. 😄

I did not find any mention to Angle in the latest docs for building godot. Should I open an issue in godot-docs about that?

Yes, docs weren't updated.

The relevant build flag is angle_libs=/PATH/TO/STATIC/LIBS, and pre-built static libs are available at https://github.com/godotengine/godot-angle-static/releases

Since the issue is pretty much solved, should I close this, or should it stay open for another reason?

Could we include those DLLs in the CI artifacts?

Alternatively, we can include a downloader .bat script (it should work on Windows 10 and later thanks to curl.exe being available out of the box).
