Summary 07715: gauntleg: Backslash toggles a strange window (debug window?), regardless of the backslash key being mapped to a control or not
Description This seems to go all the way back to at least 0.148. Pressing backslash opens a UI window with some names and values that appears to be updated once a frame. Pressing it again does not close the window, but stops it updating.

Alt+F12 does not show this window, so I did a regular PrntScr capture to show as attached.
Steps To Reproduce Wait for game to boot (ready for coinup)
Press Backslash
Observe new window
Press Backslash again
Window does not disappear

Yes. That is an internal debugging popup window which is hardcoded into the coding for the Voodoo graphics adapter. Not much you can do about it unless someone were to comment it out. Just avoid that key for mapping of such games.
