Package: gnome-terminal Version: 3.22.1-1 When grabbing one of the four corners of a window in order to resize it, one invariant is that the opposite corner should stay in its position.
Gnome-terminal somehow manages to violate this invariant. Grab the top left or top right corner, whirl it around, and watch the entire window move away! This happens both in Gnome sessions on X11 and on Wayland. On X11, the window's lower corner tends to move downwards. On Wayland it tends to move upwards. I'm not observing this with any other program, which is why I'm reporting this against gnome-terminal. (In particular, it doesn't happen with xterm.)
