Speed Devils lagging geometry #46

Weird title. This is extremely obvious in the Mexico track when moving left to right. Some geometry seems to be "lagging behind", detaching from the rest. See the tree tops here: image

There are a bunch of other visual oddities in this game that I suspect are directly linked to this.

Rayman 2 has the same issue.

In Speed Devils the Translucent is literally one frame (or 2 vblanks) old when Start Render is called. Probably a timing issue somewhere, but I have no clue where for now.
