I simply can not use cubase 8. I can not read anything, can not find (of course it’s hard since it is impossible to read) any way to make the text clearer. I’m seeing glittery gray on gray, tiny letters. Not everywhere, but for instance, “Plug-in Manager” … completely unreadable. “Preferences” … Left side with a white background is readable, right side, completely unreadable.

Perhaps you could post a screen shot of what you are seeing so others can determine how that compares with what they’re seeing.
