Android studio 3.0.0.18.171.4408382 has been installed. When the android studio was opened with an existing project(which is default),the screen saw just gray screen. Yet,when left-clicked or right-clicked,things seems ok,corresponding menus function correctly. Other tips:dwm is used as windows manager.I`ve no idea if this is the reason. Thanks for helping!

I changed the windows manager back to awesome,and it`s OK now,everything seems good. So there maybe something wrong with dwm.
