Godot version: 3.1 RC2

OS/device including version: root@slax

Issue description:

When trying to run Godot 3.1 RC2 there is just a blank background. I can run Godot 2.1.5 though.

My OpenGL version:

# glxinfo | grep "OpenGL"
OpenGL vendor string: Intel Open Source Technology Center
OpenGL renderer string: Mesa DRI Intel(R) 915GM x86/MMX/SSE2
OpenGL version string: 2.1 Mesa 13.0.6
OpenGL shading language version string: 1.20
OpenGL ES profile version string: OpenGL ES 2.0 Mesa 13.0.6
OpenGL ES profile shading language version string: OpenGL ES GLSL ES 1.0.16

The output after running Godot in terminal:

# ./Godot_v3.1-rc2_x11.32

It is not intuitive, that’s for certain. However, I don’t think it’s a bad thing to be able to run your editor in GLES2 while developing a GLES3 project. It may come in handy in some situations.

Still, I think any sane person would assume that if you see a “GLES2” label on your screen while working on a project, that means your project is in GLES2 mode. But converting your project back and forth every time you change the editor mode or open your project on GLES2 hardware… it would be even worse. Maybe add a caption near that button that clarifies that this is editor mode, not project mode?.. No, that’s waste of screen space, you only need to learn this once. I can’t come up with a better way to do this. This is the very first setting in the “Rendering” group, so I guess it can’t be even more obvious.

I have noticed that even if the window is blank, the gui components like text boxes and buttons seems to be working.
