Text is invisble on Ubuntu 10.10 x64 since Build 2032

It all works fine in build 2027.
But from 2032 (to 2036 included) the text is not visible, whatever file is opened.
Sometimes the text is visible at sublime startup, then some words (in my case in PHP function delarations) disappear when i mouse select it.
Sometimes, the wole file is invisible (but i can select invisble text)
