I used Vim for a number of years (I'd guess around 10), and for the last year or so I've been using Spacemacs. I think there's so much that's great about both of them, and I'll continue to use one or the other, but geez, there's so many niggling issues with both that can be offputting.
A couple of examples. In Spacemacs, the screen regularly goes blank for a while. Or if I have a file open in Spacemacs, close its window, then rename it in the OS, then reopen it in Spacemacs (by double-clicking it in Finder) it reopens it with it's old name. I'm sure there's a way to avoid this, but the fact that it happens in the first place is the issue.
If you’re on macOS, the screen blanking is a known issue that’s happening because of some unknown interaction between the OS rendering and Emacs double buffering. IIRC, the mailing list thread about it concluded saying that nobody who wanted to work on the Emacs source had the requisite macOS knowledge to fix it and it’s been stuck there for a while?
Never had the screen issue, gotta imagine that's the os and emacs.
As for the file rename issue, certainly if that's part of your workflow, it's helpful to figure out why it happens. I suspect it's due to the way filesystems work on Linux /Unix.
