PS I will await the next response from the support desk before I let them know I have resolved my issue.
AS an IT professional I have sat down and considered the issue. Firstly the fault seemed to stem from the restart of the server on 27 Jul. I have tested everything this end and the fact that I can log into the server and select the Configure realms icon and be able to select worlds, I tried a mini game and it loaded. That confirmed to me that there was no issue from my end to the server. I then loaded one of my other worlds and yes it worked. So far so good.
So the only issue was my world that I had been using prior to the restart. I went and loaded a backup prior to the server restart and then went to load it. Surprise, surprise it worked.
So there had been an error incurred when they restarted the server which either corrupted some worlds data or there is a hardware (disk) error which also effects some worlds. the restoration wrote the data to a clean area so the problem is mitigated.
The 2 days loss of work is minimal against the relief of getting my world back.
I received a non answer from them copied below with my response to them following it.
Hi Michael,
The reason for issues like this are many and can vary from player to player. Thus, making it hard for us to know the exact cause.
It can be caused by your connection such as network or ISP (Internet service provider) problems. It can also happen if you are using a wireless connection that is not stable. It may also be caused by you running multiple programs that are using your internet connection causing congestion in the connection. Another possible cause can be your firewall restricting your access to our servers resulting in a delay or loss of communication with the servers.
If the problem is caused by an error on any of our servers, it is temporary and will get fixed as soon as possible.
When you have tested for all this, please reply and let me know what might be causing the issue.
My response was:
To help,
I have a 10GByte wire network so there is no wireless stability issues.
I have checked my ISP service and is running at good to high speed..
I have closed down and done a cold boot and tried with no other programs running over connection and no change, same error message.
I have opened up my firewall and no change, same error message.
There are other users experiencing the same issue since the same time as myself so this points to a single issue which leads to a single point which would be the Realms Server or front end service.
Regards,
Michael
I have the same problem. Done the usual rebooting and even resetting router, all to no avail. Normal single player works fine.
Last successful log-in to Realms was early on 27 Jul 2016. Have contacted Customer Support yesterday with a we are working on submissions from 24th!!!!
Need more staff or there are a lot more issues than normal?
Regards
Wellcome 1.8 however as expected the rendering issue still exists. I was chatting to another user and we both suddenly remembered a similar bug in a much earlier version of Minecraft. About 1.5 ish we think. The issue was to do with graphics not been cleared on exiting one game and either going back after a change in options and another game. The short term solution was to exit fully ensuring Java was closed and then reopen and all was OK. Someone fixed it then.
This led me to a bit of playing around. I have AMD Radeon HD 7900 dual graphics cards each with 3G on board and 16 G of RAM. In short I have the grunt that should be well sufficient.
I had the same problem at greater than 12 chunks. I then upgraded my java to 1.7.0_67 and got to 14 chunks. I then upgraded my drivers to the latest 14.100 version dated 2014-04-17 and got to 16 chunks. I then changed my JVM argument to bring my max mem to 8G (-Xmx8G -XX:+UseConcMarkSweepGC -XX:+CMSIncrementalMode -XX:-UseAdaptiveSizePolicy -Xmn128M) and it did not work.
I then set the chunks to 32 saved and exited fully from teh game and Java and then went back in and low and behold 32 chunks works fine. I have trashed it with all settings on max and got the mem running at just under 3 g and all is fine and dandy. the interesting part is that if I then exit a game and go to another one without closing down Java, then the next game will only work to 16 chunks. If I go out completely and close down Java and then come back in, guess what, the other game works fine on 32 chunks. If I change down the chunk numbers, everything remains OK but if I go up again the glitch appears. But then all I have to do is save the game with the errant chnuk figure, exit Minecraft and Java and reload and all is fine.
This leads me to suspect that there is actually an issue with java and that unless you close Java down, the loaded graphics do not clear or become unbalanced. So I have a workaround that allows me to play all my games at 32 chunks with my AMD Graphics card by ensuring that I only play with a vanilla Java load and my previous video settings irrespective of how high or low the chunk setting was on last save, will work fine.
I would like Kumasasa to take a closer look at this and not just leave it as and AMD graphics card problem as it appears that there is a factor to do with Java and the rendering.

Ferran, What driver do you have for your Radeon HD7870. It should be:
Display Driver ver. 14.10.1006
OpenCL(tm) Driver ver. 10.0.1348.5
I ask this as when I upgraded to these for my 7900, it made a notacible difference. By teh way the normal upgrade checker does not necessarily work. you may have to down load the updated AMD Catalyst Centre to get it as there is a conflict in the normal checker. Have a look at: http://support.amd.com/en-us/kb-articles/Pages/AMDCatalyst14-4WINReleaseNotes.aspx.
cheers
Yeh, sorry about that Tristan and I agree it does suck. It does however lead one to the view that the whole issue is actually more one of resource usage by the game and not necessarily the AMD video cards that it has been targeted at. Perhaps the Mojang team can take a look at this?????????????
Have just been straining my brain on memory settings and for some reason decided to go and change my JVM argument in my game profile to the following -Xmx8G -XX:+UseConcMarkSweepGC -XX:+CMSIncrementalMode -XX:-UseAdaptiveSizePolicy -Xmn128M. I can now work at the maximum chunk setting of 32 with no apparent screen glitches. I have tried it at in-between settings and its stable. Oh happy days.
Crash report added as requested. Interestingly I found that though my device driver update check says there were no updates, a new version of the AMD catalyst control centre found a newer one and duly installed it. I can now go from 12 to 15 chunks with no issues. A small step for minekind.

Hi all, been playing with my settings. Running win 7 Pro 64 Bit OS in Alienware Aurora. With the latest JAva 64 Bit edition 67 and java setting inprofile to 4G max I can now use up to 14 chunks with no issues. Go to 15 chunks and it acts as going to 13 before upgrading my java version. Not sure if this helps anyone but it appears to have given me 2 more chunks. Better than nothing.
NP just glad to have helped.
Maybe I should apply for a job with their support desk. LMAO
Happy playing.
Mike
