You can see that that glide, which uses a pixel offset, is gliding vertically instead of along the transform. Just make a real fix instead of doing a bandaid fix because the bandaid fix you already did clearly doesn't work.
Also, now if you use KEEP_TOGETHER the offsets that occur when you have turfs in vis_contents don't work.
If you're wondering what the red stuff in the corner is I was testing what would happen if you put turfs from multiple z-levels on the same vis_contents. Turns out that it displays both of them. A feature I will make use of to optimize visibility.
A "real" fix is going to be mighty iffy though. The interplay of pixel/step offsets (and therefore also glides) and transforms isn't easily dealt with in this kind of situation.
