I use an Tvheadend server with DVB-C hardware to watch 1080i50 streams from my cable provider.
@Jeroen, test version for S905W:
https://test.coreelec.org/boot2k3/S905/CoreELEC-Amlogic.arm-9.0-devel-1557940097.tar
Untested, but should work
@boot2k3 I just tried your build on my S905W box, but unfortunately I still get the green/red lines (or artifacts) when deinterlace is enabled.
Does it help if I provide an sample of the content where this problem occurs? I also noticed that I do not experience this problem on all my DVB-C channels, but still they all look like similar H264 1080i50 streams (maybe some small differences in bitrate or something else?)
Some channels start with the green/red lines right away, and on other channels they ‘popup’ after ~10 sec. watching. And as I already mentioned some channels are just fine with deinterlace enabled, no weird green/red lines are visible.
Thanks for investigating this issue! 
Thanks for the suggestions - got my remote working (had an old remote.conf still in existence that I think was causing problems). I didn’t get a chance to test the deinterlacing yet (travelling for work) - will do so over the weekend though. FYI, I’ve noticed there aren’t any deinterlacing issues on the M8S Pro L when playing back from the tvheadend server on my other Kodi (Libreelec) box - the red lines only ever appeared when also running the tvheadend server locally on the M8s Pro L box itself.
OK, waiting for your results.
This lines usually appear for 1080i50 content. And more easy to repeat them when box is busy with something more like tvh server or file transfer process
@Jeroen, new test version for S905W(can be used for S912 too).
https://test.coreelec.org/boot2k3/S905W_912/CoreELEC-Amlogic.arm-9.0-devel-1557994086.tar
@boot2k3 It looks like your fix works! I don’t have any green/red lines on 1080i50 content right now. I will try to test some more tomorrow, but it looks good! 
Thanks!

@boot2k3 applied onto one of my boxes yesterday morning and so far with testing watching Live TV and Recordings in TVHeadend everything is working fine, so hopefully your fix has done the trick!
I will continue to test over the weekend, as this occurred very randomly for me previously, but I would have expected to have seen this by now.

Still looking good after a weekend of testing

Hello,
I installed the last nightly because of the changes to the deinterlacing problem for the S905w boxes.
I have an X96 mini, i tried to watch iptv over the iptv simple client in 1080i 50fps.
There are no more red or green lines but the video starts to flicker ~ every 2s.
After 1 min video stops sound is on repeat from the last 0.5s and the box doesnt respond any more.
I attached the kodi log.
If can provide more informations if u need it.

So you could see this red lines and check if it cause same flickering/stop or not.
If the same, than it could be different issue with DI for S905W and you still need to use disable deinterlace. If no such issue than collect full logs(dmesg and kodi) for both 9.0.2 and nightly to compare. Don’t choose “disable deinterlace” in both cases.
Thanks for your fast reply 
With every release before 9.2 i had to disable deinterlace because i had the problem with the green/red lines.
With version 9.2 i have the same problem with the flickering/stop.
Now i am at the latest nightly and its the same like 9.2.
I build a cooling solution for my box so it is not overheating.
What i tried:
overclock gpu
change cpu govenor
tried different settings in kodi player settings
coreelec version: nightly_20190522
dmesg:

kodi log:
https://pastebin.com/zEGwuNMu
If you need more i can provide it.
Please execute command dispinfo while watching iptv and send me a link
Try to set default refresh rate to 50Hz to minimize screen switching for IPTV
And in PVR/TV settings ->Playback->Fallback Framerate choose 50Hz if most of you IPTV is 50 Hz
I set your settings.

sleep 10;In that case for now I don’t know how it can be fixed. Something is wrong with DI in S905W.
Several users on new 4.9 code have also ‘pre_de_irq’ issues sometimes.
So only solution now for this issue is “disable deinterlace” feature.
As it will be fixed in 4.9 than it possible can be include in 3.14 code
Thank you for your time and effort!
I will look at it again when the new kernel is out.
Have a nice day
You welcome
