[0.10.x] underground belts, vibrating screen

[boro]

I don't know if this needs fixing but I thought I'd let you know anyway. Do not let it interfere with release schedules please

When you stand on an underground belt entrance and bump in to certain objects, that causes the screen to vibrate and appear fuzzy. Especially noticable with fast/express underground belts and zoomed in.
The situation where this comes up most is when you have chests on the same row as your belts and use underground belts to pass them. (and you stroll around your base checking things out and inavoidably get transported by standing still on belts)
On the screenshot, objects to the left cause this vibrating, objects to the right do not. Tested in 0.9.8 and 0.10.12.

I can only notice that vibration on the closest of zoom levels. I'd never have noticed if you didn't say anything.

With the slow underground belt I can notice it up to default view, with express underground belt all the way zoomed out.

It looks like the fast inserter above me is grabbing the iron ore, but instead it's flipping around like crazy. The 2 chunks of iron ore are dancing between the 2 pieces of belt.

Hm. This is, cause of the item/character is moved in a frequency of 30 Hz from one tile to the other and back due to simulated "physical" reasons.

That's expected: the belts are pushing the iron out of reach of the inserter and then back again. When the items are In reach the inserter tries to grab them but by the time it moves they're out of reach again and it repeats.

It is partially not a bug and partially solved as the transport belt to ground no longer moves non-item objects.
