Whilst Compiz is enabled if a gnome-terminal window is drag-resized the legend displaying the size during dragging is displayed as blocks rather than numbers. The same thing occurs to all windows if the Fusion plug-in resizeinfo has its 'always_show' property set.
Changing resizeinfo's 'text_color' to something other than black reveals that the legend is being rendered but the background of each character block is also being filled (with black).
So by default it draws black on black, resulting in the impression that only blocks are being displayed.

libcairo: statusexplanation |
Tracked down the apparent cause to libcairo's debian/patches/02-cairo-1.4.8-lcd-filter-2.dpatch.
The bug reveals itself if sub-pixel rendering is enabled and rgba_order 'VRGB' is selected.
$ gconftool-2 -a /desktop/gnome/font_rendering
rgba_order = vrgb
antialiasing = rgba
dpi = 96
hinting = full
Changing it to any of the other options (vbgr, rgb, bgr) using
$ gconftool-2 -s /desktop/gnome/font_rendering/rgba_order -t string "vbgr"
and restarting Compiz (or disabling/re-enabling it) will clear the issue.
Working on a fix. |

Since upstream can't make up their minds on this I've un-assigned myself - it doesn't look like this is going to be addressed any time soon. I had been hopeful of some kind of resolution that we could implement as an SRU. I've added a bug-track link to the upstream bug report.
When using VRGB sub-pixel hinting this issue will occur. The easiest workaround (one I've used with Gutsy, Hardy, and Intrepid) is:
gconftool-2 -s /desktop/gnome/font_rendering/rgba_order -t string "vbgr"

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. |
