I've tested the SWF file with Gnash 0.8.10 (with various backend)
and able to confirm the issue.

This is a side-by-side comparison result, all from Gnash 0.8.10:
You'd see that:
- AAG (default) produces prettiest result, but with incorrect glyph.
- Cairo produces correct result, though edge is not entirely pretty.
- OpenGL also produces correct result, but with no antialiasing,
and result is not positioned in the middle.

This screenshot and debug logs (verbosity 2) also attached.

Gnash: gnash-0.8.10 (source)
System: Debian GNU/Linux 6.0 "Squeeze" i386

(file #29853)

Hi there,

in the attachment you can find a logo in SWF format that is rendered fine by cairo, but it is wrong rendered by AGG.

I cannot say what happens with OpenGL, because it seems not to be an option for me.

Many thanks for your help,


Pablo Rodríguez <ousia>
