Spacemacs hangs under normal usage (moving the cursor, etc)

[auser]

I've been using spacemacs for the past year and have had very few issues, but when reseting my spacemacs to head and reseting my .spacemacs file, all of a sudden I get 'hiccups' when moving the cursor where spacemacs pauses and hangs briefly until it can "catch" up. It basically renders spacemacs useless for development right now. Has anyone else experienced this problem?

My emacs port was installed via Homebrew:

brew install emacs --HEAD --use-git-head --cocoa --srgb

Any ideas?

[StreakyCobra]

Do you have the possibility to try emacs 24.5 with the same config? We know there are some problems on emacs 25, it may be the case here.

[auser]

Thanks for the suggestion/idea @StreakyCobra

When running on 24, I get the following error (I think this is a helm error?)

byte-code: Symbol's function definition is void: eieio-make-class-predicate

[StreakyCobra]

Hum, can you try to move (or remove) the ~/.emacs.d/elpa folder, byte-compiled code could be different between versions.

[auser]

@StreakyCobra Unfortunately it doesn't fix it. I ended up recompiling/reinstalling everything and the problem still persists.

EDIT: I didn't see your earlier suggestion. I'll try that

[StreakyCobra]

Yes, when installing another emacs version it's better to recompile all bytecode files because it may be incompatible. Removing the elpa/ dir force redownload and recompilation of packages, but you can also do: M-: (byte-recompile-directory package-user-dir nil 'force) RET

[auser]

@StreakyCobra Okay, after a complete uninstall/reinstall, the problem still exists.

I've noticed that it happens after I Cmd+Tab. It exists on both 25 and 24.

Additionally, I'm using the clojure layer

[StreakyCobra]

Clojure + Emacs 25 + OS X :wink: Nothing that I'm using, so I don't know how to help more, sorry :pensive:

I had considerable lag in spacemacs for pretty much any input. Finally, after disabling minor modes one by one, I found that flycheck caused the issue. After disbling spacemacs is really responsive. I'd sugggest trying a similar approach to isolate the issue. See also #1114.

Hey guys,

I also have those "hiccubs". Mostly when I'm navigating down/up for a while. I switched to Use M-g g to jump directly to a line number but that's not always the best solution for me.

[voeler]

@xetra11 Did you try disabling the syntax-checking layer (flycheck)? Alternatively disable all layers and see if the problem persists.

[CMCDragonkai]

I'm getting as well, but I don't have the flycheck, and I'm running spacemacs 64 bit on Windows 10. Every once and a while, the cursor just hangs when I'm trying to move it up or down. It's stock spacemacs with just some of the default layers installed (uncommenting some of the lines in the spacemacs config file).
