For some reason, when I click a button, be it in the customize buffer or hyperlinks in org documents, it sometimes works, and other times the whole buffer shifts to the left like a single pixel and it sets a mark (it says so in the minibuffer). The button is not clicked in those instances.
Has someone experienced something similar? Is there a way to improve this?
Interesting. I’m still just guessing, but I notice that you’re using relative line numbers which means that there’s a potential difference between the amount of space needed to show the relative line number vs the absolute line number, and that might explain the shift in display. Can you reproduce this when using absolute line numbers? If not, that seems to narrow down the trigger scenario, which will be helpful information for an upstream bug report.
