I'm having a very strange bug when using emacs remotely. Currently my .emacs file is commented out except the lines defining the theme:

When i start editing a file, i experience a severe display bug that prevents me from reading an edited line until i quit and reload the file, It is difficult to explain, but i've attached a screenshot of a line of text before and after typing the string "bannana bannana bannana bannana" at the start of the line (and pressing no other keys). I can start emacs with the -q flag to avoid this error, but I would prefer not to as I very much like having the theme set. I've also tried enabling a theme after starting with -q (in case there is a typo in my emacs file), and I get the same errant behavior.

Has anyone here encountered a bug like this before?
