@Gerry Boland (gerboland) @Daniel van Vugt (vanvugt) I just want to clarify the confusion you have with nVidia drivers. When I reported the bug I encountered it on Xenial (without Mir) and the title changes covering Zesty (Unity8/Mir) where made by Daniel along the way (comment #3). Thus my graphics drivers mentioned in the bug description should not be of any importance for Mir. Running webbrowser-app on the original machine (Ubuntu 16.04 with newest updates) now creates and destroys the window almost immediately.
