I use the quake drop-down terminal a lot.
Recently, it started to switch between tabs when I use my mouse wheel anywhere in a terminal.
Usually, I use the mouse wheel to scroll within the terminal, and not to switch terminal tabs. Now the behaviour ist, that it does both: It passes a scroll event to the currently opened terminal tab, and switches to the next tab, and so on, until I stop scrolling.
What might have caused this, and where can it be switched off; where is the corresponding configuration switch?
I am not sure if this is a guake issue at all or some GTK3-"magic" which was silently imposed upon me with some upgrade.
In the settings of guake (Right click -> "Preferences"), I don't see that I have mouse scroll assigned to any action, and especially under "Keyboard shortcuts", "Go to previos tab" and "Go to next tab" are assigned to <Alt>+<Left> and <Alt>+<Right>, respectively.
I am using guake version 3.9.1.dev0 (according to guake --version) from Arch Linux).
I am not using gnome, but I am using xfwm4 as window manager, without a desktop manager, and lightdm as session manager. I do start up everything I want to have ready at Xorg startup via ~/.xinitrc.
I have already reported an issue upstream: Here.
Regards!
