[Linux][OpenGL][4.9] Black screen in Editor's viewport when use -opengl4

I mentioned in several reports about this problem, but to insist on a speedy solution to it I decided to open a resporte too.

The problem it’s easy, when i init the editor without any command they works fine:

It’s ok, not very good, is very slowly when we charge any external process, like create a new project, for example, or create a blueprint or custom class. But, for this isse it doesn’t matter.

The problem happend when i use the -opengl4 command for init the editor, i get a editor with a blackscreen in the viewport, i don’t know why happen this:

But when i play the level i can see all very clear:

And yes, i tried creating a new project and i get the same error.

I see that this bug presets since Unreal 4.5 and i think that is very incredible that doesn’t fixed yet. So bad.

This is my especifications:

  1. Ubuntu 15.04
  2. nVidia 525M
  3. 6GB Ram
  4. glxinfo | grep “OpenGL version” → OpenGL version string: 4.5.0 NVIDIA
    355.11

I’m doing now the fix recommendations.

Thank yoy very much for your great work, i like Linux and i like this great engine :D.
