Comment 3 for bug 1167234

I am not sure what you mean with "--opengl=false" because I do not use a command line. However, in the advanced option, OpenGL is disabled. If I enable it, all the buttons, windows etc. are black (see screenshot), but clicking is still possible. (I guess that OpenGL does not work properly is already known?)
I have tried to change some other options (fullscreen, resolution), but that did not affect the problem.
My graphic card is "Intel(R) HD Graphics", if that matters. If I need to provide more information, tell me which one.
