terminal windows become invisible while zooming in using alt + scrollwheel
I'm not sure if this is the default binding: I use another one. I have a feeling that it is. It might be super + scrollwheel.
The desired effect is to zoom in on a part of the screen, and you can move around with the mouse. Unfortunately xfce4-terminal consistently becomes invisible while zoomed in, reappearing when you go back to normal level of zoom, i.e. none.
You can still type in the window, and even move it around, but you cannot see it.
