Comment #15 by MoMaT demonstrates a non- compiz scenario. My comments #2 and #10 demonstrate the issue with Compiz enabled. The underlying issue essentially seems to be: where should sub-pixel rendering should be done - in libcairo or in the font renderer (FreeType in this case) ? There have been two versions of the Ubuntu patch in libcairo/libcairo2. Reports seem to suggest that both versions may be responsible for the VRGB problem (however, that supposition needs checking - see Bob McElrath's comment #19). We need to be aware that libcairo (libcairo 1.5.4 in Universe) and libcairo2 (cairo 1.6.0 in Main) are similarly patched and will need similar fixes.
