A problem I have with #Gnome / #GnomeShell: the resize handles of windows are like pixel perfect. There's maybe 3 pixels of space where I can start the drag from, and sometimes the click goes through to an underlying window even though the cursor is a resize handle.
@ashwinvis and @nicd, when I was using Gnome on desktop I recall that was also possible. It seems to be a hidden settings, which can be accessed via Gnome Tweak Tools or supposedly dconf-editor.
