Is this happening with or without contact shadows turned on?

Does it happen on the default startup file?

Happens on blender startup with default blend and when i open different blender 2.8 Eevee files. Have not checked on contact shadow.

@AKIRA_SAN Could you provide the output of running blender in a console with the arg --debug

@AKIRA_SAN you need to run blender from the cmd, and pipe the output:
blender.exe --debug 1>out.txt 2>err.txt

Also can you do the same with --debug-gpu

Ive compiled the latest master, 2.8 in debug;
gpu debug err: https://drive.google.com/open?id=0B6yNvVGWiWysUl9UbGhfd1N6TE0
Ive also noticed, that by switching from Eevee to Clay and back to Eevee will crash blender, but thats a new issue.

This solves the black cube for me on macOS 10.12.6 + Intel Iris 6100.

I don't understand the code well enough to know if this is safe to commit though.

Adding the uniform fixed the bug.

So I got this issue too. I usually work on a potato pc with no graphics card. This computer seems to be completely incompatible with blender 2.8 and eevee. I switched to a PC with a nvidia 1060 and enabled CUDA and now blender works perfectly.

I know not everyone will have this option, but its a start.
