Font problems in Google Chrome

Hi there.

First of all, as previously stated, great looking theme! Been using this for two different projects now – with truly good looking results.

However, there is one little annoying detail. Sometimes, it seems, that the font-sizes do not load properly from the stylesheets. (no changes made to the fonts or sizes in either child- or mothertheme)

Here is an example:

How it′s supposed to look:
Small letters.

How it sometimes looks before refreshing the page:
Big letters.

Any thoughts on how to fix this?
