I have a space in my user name, so the user folder is Emiya Shirou, why chrome won't start, and interpret commands (to the shortcut) when you have things done like that?

i mean commands like
--enable-gpu-rendering
--enable-video-layering

because of that for example the new optional way that chrome can display tabs in left sidebar doesn't working... because chrome won't start/don't see itself/you can't do a shortcut that way...
