Breaking the bedrock below an Ender Crystal (in the End) creates performance drops, rapidly flickering light

Resolved
Fixed
3

To reproduce:

  • Go to a tower in the End, in Creative Mode, and have the Shift+F3 graph open.

  • Destroy the bedrock below the crystal (being careful not to destroy the crystal).

  • You'll see the Fire block will become 1-sided (facing south), as it isn't resting on anything on its bottom (may or may not be relevant).

  • You'll see the Fire block disappear and appear rapidly, causing the light to flicker rapidly.

  • The 'Tick' portion of the pie will increase, and you will start to experience lag.

  • Quit to the launcher, and in the Dev Console you will see a lot of

    • "Can't Keep Up!"

    • "Something's taking too long!"

You can make the lag go away by putting a block (doesn't have to be bedrock) back under the crystal.

Didn't occur before the 1.8 snapshots. The presence of the crystal prevented a Creative player from hitting it.

buggy behavior changed slightly, but degradation and Game Output messages remain in 32a.

Fixed!

As of 1.8.1 pre-3, the Fire doesn't behave strangely, and there isn't any additional lag.

"Something's taking too long!" messages remain, but appear to be unrelated to the Ender Crystals; the pie chart is really unaffected by breaking the bedrock below the crystal.

Thanks.

Oops.. I was wrong about it being fixed. It isn't fixed. (I was breaking the wrong block...)

Confirmed for 1.8.1.

Also in 1.8 (MC-70970).

Not happening in 15w31a!
