1. create a javascript file that contains lots of codes which is over 10k lines
2. type zm to close all folds
3. the problem appear (cursor is get stuck and can't get anywhere for a long time, can't do anything actually)
4. i have tried increment fold lines step by step, cursor becomes slowly when folded lines over 1k, and got stuck when over 10k ...

Expected behavior

cursor should move easyly and timely as usual

Actual behavior

cursor stuck for a long time (about >1 minute). it is annoy, how can i fix this

where's your 10k code?

where's your 10k code?

javascript.txt it's here. sorry for my carelessness.

[kevinhwang91]

can't reproduce it, maybe your some plugins are the culprit.

[ZG-N1]

Thank you for your hint, I have test my all plugins.finnally, i find the culprit plugin. when i disable the plugin called "nvim-lspconfig", the ufo works perfectly. but i don't know how to enable lspconfig correctlly. after all thanks.

It may help if you upgraded your neovim.
