But when I pasted my text in Lithuanian to note, it's almost unusable. Same situation even after converting all text to plaintext (so there is no notes or links to missing footnotes, only text). After buffer-anonymize performance is much better, like with notes in other languages. So, problem is with language, I think – Lithuanian has letters ąčęėįįšųųūž. So I copied public lithuanian text to the note. Strangely situation is better (but worse than with English or Russian notes).

It is working well while insets are closed (regardless of file length), but it is completely unusable after selecting "open all insets" in view toolbar even after anonymization, without Lithuanian letters. Branch inset with several opened huge notes in it is performing extremely bad. I can barely use mouse or touchpad to scroll – it stalls and scrolls after quite a long time with CPU usage rising drastically. I was trapped several times when searched word was in a big inset in my usual file – search opens inset to show a word and it consumes some time to get out of it :).

I noticed some other strangeness with the attached file. When I open the 
branch and both of the contained note insets, I cannot scroll down from 
the top anymore. It just keeps jumping up again.
