Thu 04 Aug 2022 04:46:18 PM UTC, original submission:  

I found a quite significant source of poor performance. that on larger document makes working impossible

Reproduced under:
- Windows 10 running official TeXmacs 2.1.2
- Debian Linux (running in WSL) running TeXmacs 2.1.2 SVN13888 from https://build.opensuse.org/project/show/home:slowphil:texmacs-devel

How to reproduce:

- Have a reasonable length document
- Try typing or moving cursor (1)
- Display the preamble
- No need to edit anything
- Close the preamble
- Try typing or moving cursor (2)

The movement in case (2) is much slower than in case (1).

Solutions (choose one):
- Close Texmacs and reopen Texmacs
- Close the document without actually closing Texmacs and reopen document

On smaller files this is not very noticeable but on larger one it becomes impossible to continue working. Attached is an example.
