Bug description:
Binary package hint: libcairo2
There is a long-standing problem (Gutsy, Hardy, Intrepid - possibly
Jaunty too) with sub-pixel rendering which affects metacity or compiz
composition (see the images attached to this bug) when VRGB is chosen
as the sub-pixel format. 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.
