I'm having an issue where I click on an icon in the GNOME favorites bar aka Ubuntu dock (to open a window, etc.), but instead of just opening the window the icon immediately goes into drag mode for repositioning. I know that holding the click on the icon causes drag mode, so I checked my mouse and click timings, but those all seem to be in order. I've also made sure everything is up to date OS-wise.
Any other ideas for a fix?
I'm running Ubuntu 18.04 LTS with GNOME 3.28.2 on a Thinkpad T580, and I can provide other info as needed.
