A few months ago qtmir used to replace the key repeater by replacing mirs dispatcher. And key repeat is not disabled within the nested server. So both the host and the nested server are producing repeat events. Now due to a logic error inside mirserver the key repeat dispatcher is not hooked up to the input device hub when running inside the nested server. The input device hub would tell the key repeater when devices get removed - i.e. due to vt switching. So it never notices that the devices go away continues to produce those events indefinitely. This applies to all currently pressed buttons. I.e. you can open an edit field and press 'w' while simultaneously pressing Ctrl+Alt+FX to switch to another VT. On return 'w' will be repeated indefinitely.
