brent Never heard of it. Interesting component.
Libvte has a very impressive list of reverse dependencies. A change there should affect nearly every terminal emulator that's used with Solus.
However, I'm puzzled by those cases in which two differnt terminal emulators (one the DE default and the other the optional Terminology) work differently, although they're both reverse dependencies of libvte. Perhaps Terminology handles fonts independently, and only uses libvte for other functions?
The best non-Solus performer in this respect is, in my opinion, Ubuntu Budgie (10.6.1) and its Tilix terminal emulator. Its text descenders are sharply and completely visible even at the bottom of a page.
