Hi,

I’m not sure if this is a pango or cairo bug, but I’m starting here. See
the simple attached program that renders a string using cairo and pango.
It is written in python, but the same behaviour was observed in an C
package first (binary package sm), so it is a bug in the C libraries.

It should print ":-)" in relatively large letters, but I get the output
as in the attached image. This does not happen at all font sizes, but
only for certan spans of sizes.

This bug is relatively bad for users of screen-message (sm), because it
makes it non-reliable.

Thanks,
Joachim
