🐞 Scrolling choppy and syntax highlighting slow to refresh

[szymonlopaciuk]

Description

Scrolling through any file (checked different languages, no custom LSPs installed/enabled) produces slow and visible refreshing of syntax highlighting, which presumably causes scrolling to look choppy and not smooth. See the video below:

To Reproduce

1. Open any long-ish file
2. Try to scroll through it

Expected Behavior

Syntax highlighting should be preserved during scrolling. The scrolling should be smooth.
