This error ("intel_do_flush_locked failed: No space left on device") does also affect Gnome Shell users with said Intel Graphics. Gnome Shell dies upon this and no keystrokes are forwarded to applications, although mouse and application menus do work. This happens with on a single monitor with approx. 10 to 15 applications/windows open on multiple workspaces (usually 3 or 4).
