WFM. At lest I see no obvious non-straight lines.

Are your lines jagged or misaligned, or what do they look like?

Are you able to attach a screen shoot so everyone knows what to look for?

Thanks!

I didn't see something like that in comment 1, and this is still a WFM in:

FWIW, Nicholas Nethercote (developer of said feature) already knew this, and didn't think the added work was worth it (if fixable at all) :

It's just ASCII art, AFAICT it happens just because the in font used on Mac the unicode box drawing chars don't line up properly.  Which seems like a Mac font bug.

Bug 654917 is the proper fix for this.
