There are some odd line spacing issues. The line spacing is set at 21px in the demo, but this makes spaces between the lines. Setting it to 18px will get rid of the spaces, but now mouse coordinates are all off since they are based on the 21px line height. Worse, some apps (like htop - see screenshot) display the status bar half-over the bottom of the terminal. I think these are related.
