How to change size of info bubbles

[DirtyFinger]

Hi,

I'm running a pretty unconventional resolution (3840x1024) thanks to the TripleHead2Go and I had to fix a couple of zoom settings to make it playable.
The one thing I couldn't figure out was how modify the zoom behaviour of the "info bubbles" (the round indicators that also appear when pressing CTRL-R).

Any idea what value controls them ?

Thanks!
