It freezes when I write about 500 lines. In console I have an error: ‘TypeError: child.chunkSize is not a function’. I tried to paste many lines in the example editor on codemirror.net and even 10000 was ok. Does anybody have any thoughts about this problem?
Sounds like you’re using version 5.15.0, which has a bug to this effect. Upgrade to 5.15.2 or 5.16.0 to solve it.
