In the wrong place at the wrong time, it snapped cleanly in two; the only remaining piece is the back button.
Note: Both Joy-Cons connect without issue when detached. That's reassuring, but does that mean it's repairable?
I haven't tried detaching the remaining stuck part; I want to be sure before doing anything else.
On Switch, and perhaps on other platforms, when I'm in "Graphics" mode (the highest resolution), I've noticed that certain details, like the backfire on vehicles with exhaust pipes at the rear, are completely lost. I also suspect it's related to the camera's distance; just look at other vehicles, and they display the details perfectly.
I imagine it's a graphics system setting that prevents this, since the problem doesn't occur in "Performance" mode. I'm surprised this hasn't been reported before, even here.
