I can't edit description, why?

This is a known limitation of the new compositor system which operates on the pixel level. Doing downsampling in such design is note possible with a nice antializas. There's no easy solution for this problem and hopefully @Jeroen Bakker (jbakker) will address it in his current project.

Thanks for the report, but it's not currently considered a bug.

P.S. You can't edit description because currently in Phabricator it's not possible to grant edit role to the author, meaning either you can't edit own tasks or you can edit everyone's tasks. This will be addressed at some point in the future.
