    • State changed from “new” to “invalid”
    • Assigned user set to “rsms”
    • Tag set to syntaxhighlight, ux

    This is by design.

    I had the following two options to chose from:

    1. Let syntax parsing and highlighting occur in the main thread and thus block the UI while calculating and also make it slower (since we would need to "yield" in the main runloop once in a while)

    2. Let syntax parsing and highlighting occur in a background thread.

    Number 2 was chosen. What you see is the time in between you typing a character and the parser & highlighter working and finally applying it's result.
