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).

What shall I do to experience bad performance? What is your operating
Manjaro linux, sway, wayland laptop Lenovo X1 yoga (1st generation) (CPU: Dual Core Intel Core i7-6600U (-MT MCP-) speed/min/max: 699/400/3400 MHz Kernel: 5.10.7-3-MANJARO x86_64 Up: 7h 04m Mem: 6805.1/15417.2 MiB (44.1%) Storage: 476.94 GiB (90.0% used) SSD NVMe) Open note inset and scroll down (I'm scrolling with touchpad), note content must be wisible in Lyx work area. The faster scroll, the higher CPU usage, but document moves very slowly and with quite a big delay and with big jumps. wayland can be the culprit. I opened lyx in xwayland mode and I can scroll through the note only slowly – after scrolling fast document are thrown back to initial position. CPU usage about 70%. In wayland – 99% if scrolling is intensive, up and down.
