Created attachment 327314 [details, diff] line-spacing-fix With same font line spacing used by urxvt is larger than one used by xterm. Using resource lineSpace it's possible to even more increase line spacing, but not possible to decreased it (using 0 or negative values). I've found patch for this issue in Arch AUR - it works ok. Please consider adding it to portage (probably activated by custom USE flag like most other patches in current ebuild).
Please send patches upstream.
(In reply to comment #1) > Please send patches upstream. Usually I do. But not this time: At first, I've no idea is this patch does something right or wrong. It makes urxvt work in same way as xterm, but that doesn't mean xterm's way is right and urxvt's is wrong. I'm in no way X expert and can't decide this on my own. But even if it does something "wrong", I think it's good to keep it as optional USE-flag controlled feature. At second, I had conflict some time ago with Marc Lehmann (urxvt author) and he blacklisted my email, so I'm not really right person to send patches to him. And last, I think it's better when patch author send it upstream (i.e. someone from Arch AUR in this case), because he at least have an idea what and why this patch does and can discuss this with upstream in case they'll have questions about it.
