Hacking Found interesting glitch on screen while shutting down Wii U - potential exploit?

[GoldenSun3DS]

I shut down my Wii U while it was in the middle of closing SM3DW, and a weird corrupted-looking effect appeared on the Wii U gamepad just before it shut off.
Could this potentially lead to an exploit, or is this nothing?

My Wii U is on whatever latest firmware was on New Super Mario Bros U, Super Mario 3D World, Mario Kart 8 or Donkey Kong Country Tropical Freeze (never been connected to internet).

It's just the controller losing the video connection and showing garbage. (i.e. definitely nothing)

But when I shut it down from within a game or the home menu, it doesn't do this.

Probably because during the period when the Wii U Menu is loading, there is no power button handler registered, so a hard shutdown happens. But in the other 2 cases, the app has already registered that handler, so the power button being pressed makes it shut down the Gamepad display.

Still worth mentioning IMO.
Even if things like these end up being meaningless, what if something someone noticed actually turned out meant something and could lead to an exploit, and no-one talked about it? No-one would ever know.

I did another test from within a level instead of within the VC minigame, and it did the same thing as the first video I posted.

Don't think I need to post it since it's the same thing but in a different part of the game, unless you want me to (it's already recorded).

I shall refer you to this thread. It has a lot of usable info in it which may help you with this exploit that you have found

I suspect that it may have to do with the VC emulator. It may not have power button handlers properly configured. Either way, I doubt it's exploitable. Even if we can run code with this, the system will shut off after a few instructions.

the streem was cut and and u got a bad frame. (missing data) absolutely not exploitable
