Random, unsolicited (no mouse or keyboard input), scrolling.

[RodHorning]

Web browsers (and I've also noticed this in the text editor) will randomly scroll up and/or down. This occurs without mouse movement or keyboard input.

Could you please share a complete list of applications that are affected (sounds like there is more than one web browser)?

[RodHorning (rod-horning)]

Firefox and Opera browsers. I've noticed it in NANO and from the GUI Software list also.
