MC-64426Chunk loading Graphical Glitch
I wanted to enlarge my render distance above 6
what actually happened was that after 8 chunks all the chunks were spawned around where i was looking when i moved i say the next chunk repeated over and over i made a video and attached it below
Steps to Reproduce:
1. turn video settings to the lowest except the brightness and Gui (kept at normal
2. set render distance to 8 or above
3. ...
Environment
Windows 8 java version 1.7.0_65

What is your Video card? maybe try and update or even down grade the driver
i have an AMD Radeon HD and i read on forums that AMD cards arent working well with the snapshots and apparently others have been getting the same glitch
I didn't notice this particular glitch until the day 1.8 came out, and it only happens on one of my computers: an HP Pavilion dv6-6173cl Entertainment Notebook PC with hybrid video card ("high performance" card = ATI Radeon 6770M, "power saving" card = some kind of an Intel HD).
I am running 32 bit Java on 64 bit windows (this computer requires it for work reasons). The symptom only happens when the hybrid video card is in High Power (ATI) mode. The symptom does not happen on view distances less than 10 chunks, and is noticeable on view distances 11 or greater up to an allowed maximum of 16.
Have tested and confirmed on both SSP and SMP. Result of symptom is that certain chunks visually glitch out (physics and hitboxes not affected). One of the more common patterns is that entire ZY planes of 3d (16x16x16) chunks, any that contain non-air data, all try to display the same chunk contents (eg: part of a villager house; a segment of the ground with a slice through stone, ores, dirt, and dark caves facing you; dismembered leaf block arrangements, etc). The chunk contents they all simultaneously try to display can change dozens of times per second, are more easily agitated by player or head movement, and sometimes just get stuck on one pattern no matter how you move around.
Raising view distance above this seeming threshold of safety (10 in my tests) leads to the glitches becoming evident. Higher view distances induce greater parts of the landscape to glitch until at view 16 (and possibly only for locations >16 chunks from spawn) every visible chunk will glitch.
I will post a bunch of image attachments demonstrating this including one gif animation I compiled.
UPDATE: while gathering additional data for this ticket, I've somehow altered my symptom reproduction parameters slightly. 1> my safe view distance got bumped up to 12 chunks, I can't seem to repro now until I hit 13 chunks 2> in addition to chunks glitching, at 13+ mob models appear to glitch as well. They remain rectilinear, but become very large and shuffle through large rectilinear shapes temporally in sync with the landscape glitching. In fact, sometimes their body parts almost resemble landscape chunks.. save that they rotate soothly about like head movements etc and that sometimes you can recognize pig skin or skeleton texturing on the huge, intrusive (terrifying) things.
Snapshots demonstrating corrupt mob models are everything between 2014-09-03 13:27 and 13:30.
I'm sorry StevenNL2000, both what I am reporting and the other comments I see here do make this look like it's basically identical to
MC-62958, but logs show you marked duplicate and then unmarked duplicate directly thereafter.I am interested to hear your mind on this matter? Also, given that I appear to be able to reproduce this somewhat easily, let me know if there are any particular tests I could run to help gather more insight on the matter.
I have a similar problem with big stone blocks popping up overnight and ruining the landscape. Since this has been dropped, I'll make a separate report. This has happened to me in two different worlds on this computer.
@Judith Milgram
Well, the problem listed here (fixed by changing your VBO settings, as it happens) is limited to purely visual glitching.. seeing chunks appear or cycle in flashes either far away or even all around you, but the errors have no physicality. If you were playing blindfolded for example, you wouldn't even know there is a problem. All hit-detection and physical movement and block interaction or placement is unaffected.
It sounds like you are describing "big stone blocks popping up" that you can walk up to and interact with? If the erroneous blocks are actually present, you can't walk through them and you can mine them etc, then your bug is quite different from the one that we are discussing. :o
