Describe the bug
If you place a Programmable Speaker, leave it for a while, then come back to it, it will be translucent white.
Also, anything connected to it by data wire is translucent too.
The block is also visible, even beyond the fog distance, as long as its chunk is loaded.

Edit: It's not just the Speaker. Other things from II are doing it too. But nothing from IE.
Edit 2: Motor Belts are doing it too.
Edit 3: It's not by data network. The objects just happened to all go translucent at once. Might be a chunk thing.

To Reproduce
Steps to reproduce the behavior:

1. Place a Programmable Speaker
2. Leave for a while, then come back.
3. Programmable Speaker, and anything connected by data, is translucent.

Expected behavior
Programmable Speaker stays solid, the way it looks in the inventory.

I caught Motor Belts doing it too (but only from this particular angle)

This was one of the flaws of the old TMT renderer, with AMT it's no longer present.
