bug#27647: 26.0.50; Line numbers implemented natively disappear momentarily when frame out of focus

[jonas]

Unfortunately, no. The issue is consistent, but I had difficulties creating a detailed recipe for it.

For me, the issue was limited to flycheck-pos-tip which interacts with the windowing system through the pos-tip package. No modification of display-line-numbers took place.

I ended up replacing the package with flycheck-popup-tip, which displays its information inside an emacs buffer, and the problem disappeared. So at a glance the issue seem to be deeper than just being config-related, but I am not knowledgeable enough to draw any real conclusions.

I thought about that, but I'm afraid it could cause an infinite series

make editing impractical.

But if I'm mistaken, why not?

Hi Eli, Noam,

As you know from my other thread, I am unable to use gdb. As I don't know enough C to hack it myself, can you provide pointers to where I can put print statements or something like that in the C code directly to help with this debug?

Another thing, debbugs seems to have stopped emailing the bug authors!

Emails sent to just this debbugs don't reach me, like this reply[1] or this[2]. Can you guys please CC me on further replies?

@Jonas: Any luck creating a recipe for this?

@Eli: This problem is consistent, though not consistent enough to yet create a recipe. But it does happen at least once a day. I am still sticking on to native line numbers and not giving up. Can this be please made a blocker for 26.1?
