Duplicate of MC-3490. Please check before posting in the future. Also please do not mark issues as private unless it is a security issue.
The mine cart flickering has been reported in MC-3490 , the sound issue has been reported in MC-1642.
Not Speaking on Behalf of Mojang:
They do test their releases, put them through pre-releases for public testing, and have opened up this JIRA so the issues can be reported. 8 million people will find the bugs quicker than a handful of developers. They do what they can, but things slip through. A code change in one place can have an unexpected result on something unrelated to the fix.

Please get the latest snapshot 12w49a where the minecart bug MC-3490 is fixed and retry.
And please attach screenshots and/or a zip of your world.

Are you relating to
MC-191?@Kumasasa: no.
This is much more sever, and happens to all sides of the cart, looking to the sides as well as both forward and backwards.
Short video that (sort of) shows the problem. On screen it appears far more extreme.
Can confirm. This is pretty nasty, as Richard indicated, its worse in-game than what the video managed to capture.
Confirmed. I did test first with 1.4.5 pre1 (non flickerung), then with 1.4.5 pre2 (severe flickering)
Additional info: Does not occur with boats or ridden pigs
does happen for falling sand...
kind of like it actually. Feels really minecraft-ish
Confirmed on 1.4.5 . Same map on 1.4.4 was smooth with 245-300 fps on powered rail. 1.4.5 on same map, same rail gets ~150fps with severe jerky minecart motion. The cart looks like it's moving in small jumps instead of smooth motion like before.
Just updated to 1.4.5 today - this is a horrible bug
OS X too: http://www.youtube.com/watch?v=Kbv1SpRQxiU
Confirmed. 1.4.5(windows)(32bit java) on 1.4.5 server(linux)
Confirmed with clients: 1.4.4 and 1.4.5 (all versions)(Win7-64bit)(64bit Java) on 1.4.4 and 1.4.5 servers (linux).
Duplicate of
MC-3727.I can confirm this bug.
Also, when I tried it with an in-game screen recorder mod, it crashed the game when recording.
Confirmed on 1.4.5, Vista 32bit SP3, Java 1.7.0_09 32-bit.
Saw this within 60 seconds of upgrading to 1.4.5, and it's quite terrible. Shows up on Windows XP and 7. I'm playing single-player survival, no mods. Also the minecart sound was glitching, cutting out or rapidly looping a small sample of the sound effect. I also noticed when playing on an older computer that is 'only just' good enough to run Minecraft, that after riding a minecart there is a big performance drop. (from ~15fps down to 1 or 2 fps!) Restarting Minecraft fixes it, until another Minecart is ridden. What is happening here? Problems like this should have been corrected before releasing the program to millions of paying players. I'm a programmer, and even if I'm making something that 6 people are using, I test every possible condition backwards, forwards and every which way, before releasing it.
@Peter: There is a separate bug report for the mine cart sound problems... which were in 1.4.2 and earlier (IIRC).
EDIT: This one:
MC-1642.Confirmed 1.4.5.
Echo on all. Sand block is dropping to lower ground, not very smooth. Cart utility is jumping. Noticeable 4-5 mm skipped frames on both.
Confirmed in 1.4.5.
Very annoying bug!
It seems that Mojang don't test their updates before release? Maybe yes.
@kumassa can you change the priority of the bug?
No, yet there is only the "minor" priority.
Important for the community is to "vote" for this bug, die push the bug to the front of the to-do queue.
Indeed, this is horrible.
Dragon Eggs when falling are just black cubes until they land.
i am experiencing this bug and it is really annoying! hope it gets fixed
@Xavier Brown
It's a falling obsidian block
Unfortuntely, this bug is polluted with multiple issues, and all other "minecart clipping" threads are being closed as duplicates of this one. I am just writing to confirm the minecart clipping/jerking problem, which occurs along with corrupted audio playback of the minecart sound effects. I hope others will open another bug on the falling entities problem, or Mojang will split this. The minecart lag problem is severe. Tested in new worlds, as well as heavily populated ones. Tested using multiple RAM allotments, different audio drivers, video drivers. No effect. The visible stutter of the cart occurs in all views (1st and 3rd person), and occurs 100% of the time. The related audio stutter is intermittent.
Any audio issues are unrelated to this issue. This issue is about the "jittering" (bouncing back and forth quickly) of various entities, most notably minecarts and falling sand. That bug has been fixed for the next release.
I have noticed a sound issue where the minecart sound keeps playing even when no minecart is moving. I thought it might have been caused by the "jittering" but if not, I will create an issue for it. Thank you for fixing this issue Dinnerbone!
@Alejandro
Such an issue already exists:
MC-1642(as noted above).@Richard that is not the same thing as what I am experiencing.
@Alejandro, that should've been fixed with 1.4.3, see
MC-6.@Kumasasa Well then its another bug because mine is in 1.4.5
I think this is the same issue that applies here (possible duplicate):
MC-3515- There's a video there I posted that shows the issue of falling blocks jittering/flickering https://mojang.atlassian.net/secure/attachment/14765/Minecraft145_animation_lag.mp4Can confirm mine carts not flickering in 12w49a.
Didn't really look at other blocks in details, but impression is that they fall more smoothly.
I also confirm that mine carts, sand, and gravel no longer flicker/jitter in 12w49a. Everything is nice and smooth.
