Thanks for pointing that out!

To be honest I have no clue what is going on there.
After lots of trial and error I have reworked how the ResizingPlainTextEdit handles new text being entered to work around this. (139abe8)
It is not perfect due to some flickering happening in the scenarios, where this bug would previously occur, but hopefully still an improvement, since the text no longer seems to disappear from the view.

Finally got to test it and seems fine, I noticed no flickering so far at least.
