This is just a case of UI inputs leaking to the emulated machine. It isn’t a bug with the Oric 1 emulation. If you have UI controls disabled and press Tab then Escape, then type a command, the same thing will happen. Yes, conflicts between UI controls and emulated inputs should be handled better, but that’s an issue of its own. There’s no point creating reports for every system where the default UI input assignments have an effect on the emulated system.

For a more obvious example, this is the same thing as “pressing P to pause also types P in the emulated system”.

The black bar appears when Tab is pressed. This equates to the ESC key on the real machine. The ORIC-1 Basic manual does not mention this key at all, but the Oric Computer magazine issue 1 says it invokes the next key to choose an attribute.

However the reason it appears in MAME is exactly what cuavas said: the Tab key leaked through the menu and got into the emulation. It's a very long-term bug in the UI.
