Firefox + Emby overheats CPU

[RedStripe 14]

Server Version 3.1.5.0

Firefox 51.0.1 (32bit)

Server Windows 7 Professional (64bit)

Client Windows 8.1 (64bit)

 

 

Core #3 load On Server with Firefox running (load determined with HWInfo):

no Emby 1-6%

with Emby (no activity or scheduled tasks) 83-89%

 

 

Core #1 load On Client with Firefox running (load determined with HWInfo):

no Emby 12-17%

with Emby (no activity or scheduled tasks) 81-94%

 

 

With Emby running on Firefox CPUs begin to overheat! Of note "ucrtbase.dll" is banging very hard on the CPU.

 

 

When Emby is run on Google Chrome this is not an issue.

 

Thx

Update to the new 3.2, rotating backdrops no longer be used in firefox.

Removing rotating backdrops will not help this specific issue. This issue is occurring immediately after starting Emby, the view is the home screen, there are no backdrops and there is no other user activity on computer

 

Thanks

I have not seen that but will do some testing, thanks.

I have this issue too in Firefox running on my HTPC. Happens even in Emby server 3.2.1.0. Completely pegs one of my cores in this old Sandy Bridge i7-2600K.

 

This does not happen in Chrome.

 

Also, strangely, this is not yet an issue on my Windows Server 2008 R2 machine, which runs in a VM, so there is no GPU acceleration there. My server is running Firefox 51.0.1 32 bit, same as on my HTPC.
