Editor rendering problems
The rendering in the editor is broken on my system. All text is rendered incorrectly like some problems with transparency and entire scene is black.
OS: Xubuntu 14.04 64-bit
CPU: Intel i5 4570
GPU: Intel HD 4600
Unreal Engine version: 4.5.0 compiled from GitHub with a small change to disable compatibility OpenGL profile as adviced in RCL's answer to Editor doesn't launch - Could not create OpenGL 3.2 context because without those changes the editor didn't even launch.
I attached the log but I didn't see anything suspicious there. Tell me whether you need any additional info.

After some debugging, I have found what's the cause of the problem.
During rendering of the text the engine calls OpenGL 4 function to set the blending mode, while my driver supports only OpenGL 3.3, thus the call is ignored.
The easiest workaround I have found is to:
After doing these steps, the text looks normal, but there is possibility that this fix has some side effects, but at least the editor is now usable.
As for the problem with black scene...
It does not occur in every scene (in the screenshot from the question is an unmodified vehicle template). It is a problem with some effect (probably using some unsupported instructions - it would be nice if the effect was automatically disabled when unsupported instead of making the entire scene black).
After changing the effects setting to medium at Settings->Engine scalability settings the scene is not black anymore. The problem with black scene occurs at both high and epic settings.
