It's not really a simple task.
Everytime you add text, it has to be relayout. That takes a considerable amount
of time.
The simplifying observation you could make is that these lines are always
appended at postion 0 of the line. Meaning a relayout is not necessary. A List
view might be better.
Then the issue is you might want the list view to wrap, rather than show
horizontal scrollbars. Or maybe not.

Subject: [Interest] QTextEdit performance
I’m trying to create a view into a rapidly changing log file. I am appending
lines to QTextEdit, and want the scrolling on the screen to be responsive. So
far I’ve been unable to achieve any reasonable level of performance with this
simple task.
Is there a better text style widget to use for scrolling log type scenarios?
Is there a trick I need to use to make this perform better?
