In the player within the editor, this “Debug Canvas” overlay is triggered simply by the key combo “SHIFT+W”, which of course means “sprint” in any default FPS controls. So as soon as I try to sprint in my game, it pops up this overlay which robs all control from the keyboard and makes the game unplayable. It shows up in the hierarchy as “Debug Canvas”.
Yes I’m pretty sure I didn’t accidentally make an entire menu. This is actually part of Unity, from what I can tell it’s called “Debug Canvas”. If you search the term on the net, you’ll find other people mentioning it popping up, although under entirely different circumstances than me. You can see an example here .
Of course I could just re-bind a different sprint button to use while testing, but surely there is a way to find out why this key combo is triggering the Debug Canvas…
I’ll give that a go, but I don’t get this problem on Windows 10 at all (I’m dual booting) on the same project, and same version of Unity, so to me this seems Linux specific.
