cairo-xcb without RENDER extension?

Hi,

I am working on the i3 window manager and we migrated drawing for
i3bar (the dock client) to cairo-xcb. Generally, this works well. We
noticed now that if we access it through tightvnc, the drawing is all
messed up.

I figured out that this is because tightvnc does not support the
RENDER extension (using Xephyr with "-extension RENDER" yields the
same result).

From the docs, I would expect that the RENDER extension is optional,
not mandatory for cairo-xcb. Is this correct? If so, are there any
tips on how we have to use cairo to make it work if RENDER is not
available?


Thanks and regards
Ingo
