I found a number of seemingly related issues but unless I missed something, none of them match my specific problem.

🎯 Subject of the issue

Experienced behavior:
Some powerline glyphs seem to be smaller than the box height. This is most annoying with the arrow glyphs used to separate sections in vim-airline (both left and right). Additionally, the left arrows also show a one pixel vertical line with a darker color.

It seems to be related to the line spacing setting in the font selection window. It is 1 by default, and the issue is exacerbated if I increase it, and disappears if I set it down to about 0.8 (but then the window is nearly unreadable of course). The bigger the font, the more visible the problem is - I used 14pt in my screenshots.

It also seems to be an issue with the vertical lines characters used in the fortune chat bubble of vim-startify.

Expected behavior:
I would expect those glyphs to align all the way to the top, but there is a visible gap there instead.

Example symbols:
 and  (separation arrows)
│ (maybe)
