Whenever I see a new interesting terminal emulator my main prerequisite to see if it's worth playing with is if it supports bitmap fonts, and unfortunately this one fails the test. I can't live without bitmap monospace fonts. I don't have a fancy 4k monitor so TTF fonts are blurry in comparison to a crisp bitmap font.
was using it for a month, cool concept, it borrows stuff from alacritty for the base, added iterm2 inline images protocol, kitty image protocol soon
but there are quite a lot of issues, mainly just really weird ones
1. splits dont feel like splits. unlike in something like wezterm or ghostty, rio uses a literal black line for splits, which cannot be controlled. it doesnt properly resize splits, which you can notice if you have like 4 splits active
2. tabs inherit from the previous tab's zoomed in height and width https://github.com/raphamorim/rio/issues/1196
3. blur doesnt work on window (not that big of an issue anyways) https://github.com/raphamorim/rio/issues/1174
4. some characters are broken (no clue how this happens) https://github.com/raphamorim/rio/issues/1192
5. has issues with iterm2 while using yazi
its a cool concept like i previously said, but it needs a lot of tweaking
