 Description   

While a piston is retracting, there is a visual glitch, see attached screenshot ("piston.png"). The wooden part which belongs on the end of the piston arm is painted on the piston base, too. On the screenshot, the green sticky blob should not be visible at all because it should be facing the stone block.

Bug exists with normal pistons as well as sticky ones.

See "expected.png" for how it should look like (screenshot made while piston was extending)

alright then

Comment by Anon Ymus [ 03/Sep/14 ]

No, see MC-59564.

Comment by user-f2760 (Inactive) [ 03/Sep/14 ]

should I create a new ticket then?

Comment by Anon Ymus [ 03/Sep/14 ]

I think that's a separate issue, but related.

Comment by user-f2760 (Inactive) [ 03/Sep/14 ]

I'm sorry to say this, but it is kind of back in 1.8
however now the base shows it's not extended when reteacting
see screenshot, it's just a split second when it's retracting

(only tested in multiplayer)

@xfallxcuav: That is a different bug, possibly MC-127. This bug is/was visual only. Confirmed fixed in 13w05b.

Comment by xfallxcuav [ 01/Feb/13 ]

It happened in 13w05a, it makes the closing mechanism of redstone portcullis not work correctly.

Confirmed in snapshot 13w05a

@Rui Santos: What you mean was already reported in MC-127.

Comment by Raja Branco [ 26/Dec/12 ]

This isn't only graphical glitch. The piston arm is actually extended and it appears 'painted in the front part of the piston body as well, but if you try walking through the piston arm, it won't let you, therefor, isn't graphical glitch only. I messed with it, and it's a directional glitch, which means that only happens when the piston is facing some directions. In this case, it may/will happen when the piston is facing: F=0(South); F=2(North).

Yeah, I already wrote that ("Bug exists with normal pistons as well as sticky ones.").

Added affected versions.

Comment by Anon Ymus [ 18/Nov/12 ]

Affects 1.4.5.

Comment by Sycholic [ 31/Oct/12 ]

yeah I was just going to post this... its changing the texture of the piston base block's top for both sticky and normal piston bases. Not too serious of an issue but this would be possibly a hit on performance (esp with large piston builds) as there is no need to change the texture nor makes sense to.

Comment by Gravity [ 24/Oct/12 ]

I see. Confirming this bug as this texture is indeed visible when the arm is retracting.

Comment by Jonathan Haas [ 24/Oct/12 ]

Attached screenshot how it should look like (made with extending piston)

Comment by Jonathan Haas [ 24/Oct/12 ]

The photo is made while the piston is retracting so the not fully retracted arm is obviously not a bug. The issue is that the wodden part (in this case with the green blob as it's a sticky piston) is painted on the piston base, which is normally just stone. I will update the description.

Comment by Gravity [ 24/Oct/12 ]

Hi there, just to clarify, I do see a graphical glitch where the base of the piston appears on the piston itself (not the arm) for a split second before the arm retracts.

From your photo, it looked like you were describing a bug where the arm would not retract fully, but now it seems clear that is not the case. If I am correct, I ask that you please update your description to reflect this information, and I'll confirm the bug for you
