Selecting/left click in text editors makes the editor jump around
A video probably explains it best: Screencast_from_11.09.2021_13_27_00
All I do here is making a left click to select to move the text cursor, then scroll a bit again, the select again.
I can reproduce this with multiple GTK3 apps so far, most easily in builder, but also in gedit.
