Jittery/slow UI on rMPB retina resolutions when using iTerm

It appears that iTerm causes the UI animations like Expose or even the Dock animations to behave slow and jittery on Retina MacBook Pros when using the abstracted retina resolutions (2x, 1.5x, etc). This behaviour only seems to appear on Spaces which contain iTerm windows, if I create a different Space with no iTerm windows on it, even whilst iTerm is running, that space seems unaffected.
Also, if I set my rMacBook's resolution to a non-abstracted resolution (1x) like 1900x1200 where the display simply scales up the screen instead of drawing pixel by pixel, the jittering also seems to disappear, hence why I associate the issue with retina resolutions.
I believe this may have something to do with my Window settings for iTerm (settings file attached). I am using iTerm usually in full-screen mode (non-lion-style), with a semi-translucent background and blur enabled.
If there's any other information you may require to track this issue I'll be more than happy to provide it.
