MC-39190Weird gravity block glitch
First place a sticky piston 1 block up in the air (basically so you have empty space underneath it), then a block on the end of it. After that, put a lever somewhere near the piston so you can control it, and leave it in the ON position (extended piston). After that, put a cobweb underneath the solid block on the end of the piston, and then put any gravity block on the solid block being held by the piston.
Now, toggle the piston so that the gravity block falls down in to the cobweb, and when it is inside it, extend it again, and you will get a weird visual glitch, where it appears the gravity block is on top of the solid block, and slightly off center. You can repeat this to make it even more off center, however, it only lasts as long as the entity is falling through the cobweb. After that the block will despawn.

Confirmed. My guess is it's a Client/Server bug. How did you find this bug? I've found one similar, but completely different.
I found this out while I was building a gravity block cannon to spray blocks randomly across an area, but yeah, have seen this occur at other times as well, just didn't know how to replicate it at the time. Hope this helps
Confirmed. The block acts as if it were not there. You can walk through it and you can’t use it as “counterpart” for placing other blocks. After a few seconds the block “teleports” to the ground and becomes solid again.
Is this still a concern in the current Minecraft version 1.7.4 / Launcher version 1.3.8 or later? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.
Yes, it IS still an issue. Not only in 1.7.4 but also in the latest snapshot.

you do know that falling blocks aren't solid anyway, right?
Falling blocks aren't actually blocks while they're falling – they're entities. It is odd that it despawns, however. I was under the impression that if it can't turn back into a block, it would turn into an item, like if a falling block lands on a pressure plate.
Confirmed for 1.8.3
Results:
Some entities dropped to items at the end of their pass through the cobweb, some appeared as blocks below (usually when a block was shoved into the side of the cobweb).
Relogging with a suspended entity, or sometimes passing through, or placing blocks around it forces an update, putting it back in the cobweb.
In a rare occurence, when an entity made it to the ground and remained an entity, it would have a brief repeating falling animation, and after a few seconds, dropped as an item.
Is this still an issue in the most recent versions (i.e. 1.10.2, or 16w42a) of Minecraft?
Fixed. Since 1.9, the falling block no longer warps to the top.
Indeed fixed with the initial 1.9 release, but that's no longer available for selection as the fix version, so 1.10.2 will have to do.
