Some special symbols are rendered small/truncated in kitty?

The number of cells a Unicode character takes up are controlled by the Unicode
standard. All characters are rendered in a single cell unless the Unicode
standard says they should be rendered in two cells. When a symbol does not fit,
it will either be rescaled to be smaller or truncated (depending on how much
extra space it needs). This is often different from other terminals which just
let the character overflow into neighboring cells, which is fine if the
neighboring cell is empty, but looks terrible if it is not.
Some programs, like powerline, vim with fancy gutter symbols/status-bar, etc.

these symbols are wide and should be rendered in two cells. However, since
private use area symbols all have their width set to one in the Unicode

these characters are followed by a space or empty cell in which case kitty

makes use of the extra cell to render them in two cells. This behavior can be
turned off for specific symbols using :opt:`narrow_symbols`.
Using a color theme with a background color does not work well in vim?
