The dot of the i seems to run away rightwards in condensed variant

[p10n]

To me, the dot of the "i" seems too far to the right. Or is this intended?

The screenshot was produced from a PDF document created with LuaLaTeX, using NRK-Mono-Condensed-Regular.ttf

Do you see the same problem with the non condensed version?

If not then it's probably an artifact from the condensation. Jetbains mono has no official condensed version, so I used fontforge to scale the font. No clue if such artifacts are to be expected or if there's some way to avoid it

Sorry for not answering yet! I was on holiday and now there are other urgent things around. I need to check again.
From memory, I did not notice it in the regular version, so either it was not visible there, or it was small enough that it did not catch my eye...
