Current behaviour

1. Create long documents in Joplin with lots of images in them.
2. Enable OCR and E2EE and sync with nextcloud (no idea if these are related. Haven't tested without these enabled)
3. Lots of lag when typing text and sometimes text will be removed while typing.

Could you provide an example of note please? (exported as JEX)

[Anvil5465]

Unfortunately the notes I've been having this issue with contain copyrighted images that I am not allowed to share, but I can try to replicate the issue in another note that will not contain copyrighted content. I'll upload that once I'm able to reproduce the problem.

Is this specific to the Rich Text Editor? (Does the lag persist if editing in the Markdown editor?)

@personalizedrefrigerator the lag is not specific to the rich text editor. Still happens with markdown editor.
