Can't reproduce with latest Git Geany. Can you try that, the Scintilla has changed significantly.
Today I reinstalled Lubuntu 22.04, and I did ``` sudo apt update sudo apt dist-upgrade sudo add-apt-repository ppa:xiota/geany-plugins sudo apt update sudo apt install geany-git ``` In Geany I did only this: I activated in both txt-documents: Document>Line Wrapping.
The issue is still there (the stretched cursor is just before the word github):
