In my experience, the bug occurs when a ThinkPad is in its Ultra Dock and is run, lid closed, using external display, keyboard, and mouse. Bug #1888695 refers to a direct connection of an external monitor to the laptop's own HDMI port. Thus the configuration is not the same. The cause may be related or identical; or they might be separate issues?
