Buffer-locally.  I suppose this will become clear as soon as the OP has
tested your "What if you turn on display-line-numbers globally".

Hello all,

I have yet to try setting display-line-numbers globally. 

The issue hasn't repeated in the past few days .. I'd hate if this has to do with me restarting my machine. (As a side: My machine had an uptime of about a year, and I restarting it fixed the problem that gdb wasn't able to access ptrace. The whole reason I wanted that to work was to use gdb to debug this problem when it occurred next.) 

After the machine restart, the gdb issue resolved, and this line disappearing issue also "seems" to have.. disappeared. 

But I cannot say with confidence that this issue wouldn't repeat again, as I haven't yet figured out what exactly caused that. 

So if I now enable the line numbers globally, I won't be able to tell if that prevented that issue from repeating, or my machine restart already took care of that. 

Let me see if this issue repeats in the next week with my current config.
