Gedit Issues since 12.04 Upgrade - Tab rendering and text highlighting

Hello,

I recently upgraded to Ubuntu 12.04 from 11.10 and I had a few issues with Gnome, it wouldnt load and I found out it was an issue with libclutter, after removing it and re-installing everything that depended on it my installation worked fine, except for Gedit..

I use Gedit heavily when programming, and I keep getting the following issues:
 - When highlighting by dragging the mouse, the cursor seems to skip over parts or reset itself, highlighting in general is just not possible
 - Tab switching doesnt always work, the new tab doesnt get selected most of the time and even if it does sometimes the text below it isnt refreshed until I scroll or ctrl-a it.

They seem to be rendering issues but reproducing them can be difficult as it sometimes works fine.

I am using official Nvidia drivers, but switching between official and Ubuntu drivers didnt help.

Any help would be much appreciated! These issues seem to be limited to Gedit so I can switch to Vim for now but id much prefer my gedit back!

Many Thanks

Edit: I have tried disabling all addons/plugins/etc
