I was experiencing this on LinuxMint 19.2 XFCE with cairo-dock-core 3.4.1, and a similar machine at work (but not sure the version of that one) .
The deb in the repo is just out of date. I built from source (3.4.99.alpha1) and it has resolved the problem. -- You received this bug notification because you are a member of Cairo- Dock Devs, which is subscribed to Cairo-Dock Core. https://bugs.launchpad.net/bugs/1386200 Title: middle click on dock task bar icon open app twice Status in Cairo-Dock Core: Confirmed Bug description: $ cairo-dock -v 3.4.0 on archlinux in gnome-shell. When I middle click on gnome-terminal (for example, other apps are same), two new window of gnome-terminal is launched instead of one ( the correct behavior). I think it is a regression from previous version. The debug output (cairo-dock -l debug) is attached, I middle clicked gnome-terminal launcher in the end of the debug logging.
