I was making a glitchless TAS of SMB and I found this: . What happened? If anyone wants, I can give them the .fm3 file.

I didn't know you could clip in like that, but i know that you can clip into walls underwater like this https://www.speedrun.com/slb/run/z11jk1jz

It might have someting to do with my subpixels, because I did use L+R in that room, as you can see on the right.

You can get the same clip by using AEPLLG + Turbo.

You wouldn't be able to clip like that on NTSC, but apparently for some reason you can on the PAL version (don't know why tho)
