See the highlighted part from the section of the README.MD called "Prerequisites (Read this if you are having issues!)":

Notice (Text rendering issues)

If you are having problems with the characters in the graphs not looking like they do in the screenshots, it's likely a problem with your systems configured fallback font not having support for braille characters.

See Terminess Powerline for an example of a font that includes the braille symbols.

See comments by @sgleizes link and @XenHat link in issue #100 for possible solutions.

If text are misaligned and you are using Konsole or Yakuake, turning off "Bi-Directional text rendering" is a possible fix.

Characters clipping in to each other or text/border misalignments is not bugs caused by bpytop, but most likely a fontconfig or terminal problem where the braille characters making up the graphs aren't rendered correctly. Look to the creators of the terminal emulator you use to fix these issues if the previous mentioned fixes don't work for you.
