This is a DisplayPort-related issue. At the office, I was able able to try out an HDMI-only dock. The problem did NOT occur, and everything worked perfectly.
Back at home, I switched my personal dock from DisplayPort to HDMI by changing out the cables and, thus, using the dock's HDMI ports instead. The problem went away. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1970495 Title: Window manager freezes when plugging in USB-C dock with external monitor.
