Has anybody else had weird glitchiness on the Switch port of SMW?

So, for reference, I don't have a Switch. But most of my friends do, and so far, ever since the Switch SNES app release, i've seen a couple instances of a post from a friend showing some sort of glitchy moment in the game. e.g. earlier in the month another friend of mine Shared this screenshot of Donut Plains 4. I went to attempt to replicate his findings in a more buggier SNES emulator with a clean copy of SMW, but I could never get that to happen.

And then... there's this:

If SMWCentral's identity is any indicator, i'm pretty sure we ALL know that, while this game may be breakable, it's definitely not THAT easy to break.

Any ideas? Could it just be online latency causing collision detection problems?
P-switch is easy step slopes don't have good hit detection and you can easily just kick sprites through them. That particular are you can just glitch through.

Yeah, but glitching right through perfectly horizontal terrain simply with turning blocks unintentionally??? How easy is that?
Like if you stand in them? Super easy they push you down.
The glitch on the screenshot happens if you move the screen further than 16 pixels (or more than one tile). I know that some sprites have a weird interaction when they act solid and it might be caused by the Hammer Bro platform (there also exists a sprite which is solid only on the right but that's only used on the diagonal pipes in Yoshi's Island 1). It isn't exclusive to SMW, though, as other it definitively can happen in games such as Super Metroid where you can fall faster than the terminal velocity (it's commonly done in the Climb aka the original escape shaft in speedruns).

Ninja Boy already mentioned that slope detection isn't perfect (heck, a well timed jump allows you to clip through slopes).

The ledge clip happens because Mario's hitbox. You can also clip through the ground in one tile wide gaps because Mario's hit "box" (actually composed out of 6 hitpoints) is bigger than a single block and the game pushes him out of the block downwards if the top of his head is located at the bottom half of the block and he's in the air. The ledge clip has been used in a couple hacks which involve glitches (such as VIP or obviously Kaizo hacks), though it's more common with a spin jump in one tile gaps with a solid ceilling than a jump on a turn block.
Speaking of turn blocks: Only four can be active at the same time which helps the clipping. But it has got a practical use in which you can dig through turn blocks faster such as in Star World 1 but it's also easy to die given that you not only can be squished but also move faster than the screen scrolls. Hey, tell your friends to do that if they like to glitch SMW. ;)

There are many different glitch compilations but I remember that someone made a run to glitch through SMW in almost every level but don't know the name of it.

The only glitches where the emulator does affect the result are the more technical glitches such as invalid memory addresses and open bus (see the Credits Warp and related glitches).

tl;dr It's just standard SMW stuff, move along.

It's called Let's Glitch SMW.

Anyway, I've never seen that. However, I do recall being shoved to the right by jumping into a hammer bro platform. but I didn't see anything like that. It should be possible on an SNES, but I only have a Wii and no SMW virtual console on it.

The hammer bro thing seems to be a bit random in outcome and consistency. Sometimes it happens, sometimes it doesn't.

I think you can just go away and come back to fix it, and it's purely graphical to my knowledge.
Hello.
