Game rendering freezes randomly at runtime

Great news indeed, thanks for the update!

 

OMG I try new Unity 5.5.0f3 and the bug of freezing on Dual Core cpu persists and continues.
So strange to be releasing a new version of unity and still continue to exist this bug. My god unity, what are you doing?

 

Did you not read the thread!, if you did then you know...stop making drama
The fix be in patch 1 of 5.5

 

Ok, Where is the patch? Can you provide me the link, please?

 

The patch hasn't been released yet, but it will come soon. Here is Unity Patch releases:
https://unity3d.com/unity/qa/patch-releases

 

Thanks, I had already checked this link , but I did not find the patch it there so I asked, And so I was confused

 

Hi, @JakeTurner
Do you know whether whether Facebook Gameroom is impacted by this issue or not since it's also Windows based? If yes, will Unity release a new beta build with the fix for Facebook Gameroom?

 

Hi Jack
I have same freezing problem in 5.4.0f3 when I build on platform of linux x64 (Ubuntu 15.04). I wonder if it'll be fixed in the latest version.

 

I have limited experience on linux thus I can't get the callstack logs since the app is "freezed" instead of "crashed". Is there any tool we can use to produce some useful informations for you?

 

Jake, please do not apologize and do not get me wrong. You have been amazing,
I just do not understand why new versions of Unity continue with the bug, being dragged along for so long, and with each new version the same bug happens.

I find it strange how Unity works. You have been amazing and you work hard. But I think that if Unity were more organized, at this moment there was no more talk about this bug. And all new versions were released without this bug.

 

5.5.0p1 is out now, but nothing in the release notes about this issue. The fix is included in this patch release?

EDIT: Just saw it under "Core"
Core: Fixed hangs in the job system when running on certain platforms with a low number of cores e.g. older Windows Phones, UWP dual core machines.

Will download right away!

Thanks

 

The fix isn't available for Unity 5.4.3p3 ?!

 

Thank you Jake Turner, I am downloading 5.5.0p1 now. I have been waiting to solve this issue for a long time. I will test it now

 

It's there for both 5.4.3p3 and 5.5.0p1:

• (791434) - Core: Fixed hangs in the job system when running on certain platforms with a low number of cores e.g. older Windows Phones, UWP dual core machines.

 

I confirm it is resolved in the 5.5.0p1 patch.
It was good that from now on all future versions already use this fix

 

Jack, after using gdb and get parts of coredump is as follows,
I hope it's can help you figure out the problem.

Little update: a (not saying "the") infinite loop error still occurs every now an then. No crash dump, no repro-case yet. It is rare, but not so rare, that you can ignore it.

 

@JakeTurner I had the same hang issue in windows platform recently. I was using Unity 5.4.1f1. I updated my unity to 5.4.5f1 but the issue still exist. The game hangs randomly on Nokia Lumia 925 and the sad thing is that the app is live and i have hundred of users affected by this. Can you please help me out ?

 

I am facing the same issue. Should I use the patch version ?
Logically this issue should be fixed in 5.4.5f1.
@Tautvydas-Zilys , @JakeTurner Any help regarding this issue ?

 

Visual studio console shows nothing. I tried connecting the profiler but at that point the profiler also get stucks. The app freezes randomly but the issue didn't exist in 5.1.3f1 that i was using before. I dont have the crash dump. The app freezes everytime I run on Nokia Lumia 925 which is a dual core device.

 

I PMed you the link to the crash dump files. Any help would be very appreciated. Thanks

 

Submitted the bug report.
Here is the case number "Case 895766". Waiting for your reply. Thanks

 

Any update on this ?
