Sulimity-map hides the cursor near the right border, vertical scrolling does not happen.
How to reproduce:
In Emacs set: (sublimity-map-set-delay nil)
and then have a long line in your emacs buffer. The line must not fit on screen.
‘M-x toggle-truncate-lines’ enabled helps reproducing the bug more clearly, but does not matter.
Then when you move the cursor to the right, sublimity-map will hide the cursor eventually.
I think this behaviour is not wanted, you should always see the cursor.
I'm using most recent Debian jessie and Emacs-lucid, sublimity v20161214.2032:
GNU Emacs 24.5.1 (i586-pc-linux-gnu, X toolkit, Xaw3d scroll bars)
