Has happened for a long time (tested 0.120 and it still showed, but we used to have graphic imperfect flag on the driver).
So, this was promoted (flag taken off) too soon, it looks like.

yeah, it's not 'misplaced' as such either, just one layer lagging behind the other. They probably need some kind of software controlled buffering implemented, the smaller sprites are out of sync with the larger tilemap sprites, so likely part of the list gets buffered based on a CPU trigger.

the SSV video was missing many features until I did recent work on it, but I have noticed in the majority of games they do appear to need the regular sprites buffering by a frame in many cases, but I haven't found an appropriate trigger, and it doesn't seem automatic.

further driver improvements are still on my todo list tho.
