Build the attached setup, place a redstone block between the pistons and wait a few seconds. Alternatively kill yourself (/kill), fly away and come back etc. (same steps as to reproduce MC-177)
Actual outcome: Redstone block turns invisible.
Expected outcome: Redstone block stays visible.
Bug also exists for other blocks if you power them
Probably the same underlying issue as MC-177, but this particular issue can not be reproduced anymore because of changed piston behavior.

confirmed, seen it in cubehamsters video http://youtu.be/gAAoKMU6dBw
Also notice that this bug doesn't need a redstone block, on the attached screenshot the diamond block becomes invisible, too, after a few seconds.
Redstone not appearing to pulse is MC-5778
Got it now. For me, there is both the redstone block and an invisible one that occupy the same space and experience z-fighting with each other. Upon destroying the redstone block, the invisible one continues around.
I filed MC-10677 for the new weird sticky piston behavior.
Confirmed fixed for both the 2 and 4 piston setup in MC 1.5. The pistons are now behaving properly and are moving slower
you don't have to use /kill or fly away. you just have to wait or try again
