Yes, Emacs is not popular, but if you look deeper, you may find unsurprisingly that most Emacs coders are strong developers. That correlation isn't coincidental - you don't stick with Emacs unless you're willing to learn; it effectively teaches you about Lisp, extensibility, and programming in general.

Yet, they are not talking about general popularity of editors among devs, but about people who ever tried Emacs - the argument is that the majority of them try, fail and abandon it. For which obviously there's no polemical (or otherwise) data points.

I never had what you describe. The variability there could be almost random - which version of Emacs you're installing? How are you installing it? Are you trying to build it from source? What renderer are you using - there are several: Lucid, Motif, GTK, NS, W32, Haiku, Android, Cairo, Pgtk. Perhaps it's installing different renderer instead of using pgtk. Maybe it's not a bug with Emacs but with the package that bundles it for your distro?

It does seem to be an Emacs issue. But it is a specific issue that happens on the combination of your hardware and your OS configuration.
