all devices using the Realtek RT81xx for Ethernet, so HSW/BDW/KBL. HSW is the most crippled, BSW slightly less, and KBL minimally, but the mitigation is recommended for all 
 Thank you so much, that will explain a particular issue I had, which might be outside the rules of this site.
since version #0129 I been getting some white flickering artifacts on black areas of the picture.
does not happen on all videos just some.
same videos played directly on PC does not have artifacts

 I see nothing that might have introduced that. @Milhouse: something changed on driver level?

Are you really sure the version before that works?

Might be I overlook the obvious - hehe.
First decide what functions / features you expect from a system. Then decide for the hardware. Don't waste your money on crap.

No driver (or even kernel) changes in #0129, it's pretty much all kodi changes. I'm not sure what could be causing the problem, could the locking changes be a factor?

Nope. Please Nekromantik triple verify in 128 please.

Sorry my bad!
It still happens on 125 too!
So this 1 file is messed up on Kodi.

(2019-01-30, 19:37)lusephur Wrote: What workaround? And what chromebox?
There seems to be a kernel bug in 4.19 that affects Haswell chromboxes particularly hard. The work around is to edit /flash/syslinux.cfg as assuggested below. If you are really interested, the whole tale of woe played out over pages 315 to 320 or so in this thread.

 ssh root@<ip address>
<enter password, default is 'libreelec'>
mount -o remount,rw /dev/sda1 /flash
nano /flash/syslinux.cfg
<add ' pci=nomsi' after 'quiet'>
<save and quit: CTRL+O CTRL+X>
reboot  
I have a 11/2016 vintage installation of the Mr. Chromebox on an Asus Chromebox CN60 which doesn't have syslinux.cfg.  Mine uses extlinux.conf.  Nevertheless, the workaround solved my issue which was indeed painful (1.5MB/s network performance within Kodi vs. 60MB/s).

Note, I was able to get between 20-30MB/s using SFTP both before and after making this change.  Not sure why it wasn't impacting SFTP but the file manager within Kodi was virtually dead in the water.

 And 124 is fine?

Hi seems to be an issue with frameskipping on h264 content playback is not smooth
Works perfectly fine for me. So if you have an issue on your system post your Debug Log.

Not tried 124.
If it happens on more files then just 1 I will try going back to 124.
I am having the exact same problem that facecreator and czombos are having: Artifacts in the upper part of the picture, when picture is "static" (ie menu, or sometimes paused video)
Exactly as shown in their screenshots.
Sadly i cannot tell for sure which version introduced those, as i have been using the v18 testbuilds for long time, and i always had it. As it happened to change motherboard at that time, i assumed its a mobo issue, and i just ignored it as it did not interfere in a visible way during video playback.
After reading this topic, i did a test, a quick installation of windows 10, and i can tell you for sure this did not happen once. So, its not a mobo issue as i thought, its obviously related to LE/Kodi
 
My setup: Asrock J5005, 8Gb RAM, 128Gb SSD, > Yamaha AVR > Samsung JS8500 TV
Although all hw support 4K, i have no 4K media and everything is set to just 1080p ( in case this is important somehow)
@rykios can you confirm if this is present with Kodi 17.6 by testing LibreELEC 8.2.5 (download the tar file from http://archive.libreelec.tv/)? It won't necessarily help pinpoint the issue, but might still be a useful data point.

 Will try 8.2.5, downloading as we speak, BUT, i think the older versions do not suport the graphics in my motherboard, this was the reason i switched to v18 beta the day i bought this motherboard.
Asrock J5005 supports Intel UHD 605 graphics and i feel there will be an error with older drivers. Will let you know soon how it goes Smile
