Youtube lagging/jerking after some time of use. No matter which rom or kernel. - Xiaomi Mi Pad Questions & Answers

I am having a bit of issues lately with youtube, which is the main use of my MiPad.
Youtube started lagging few weeks ago for me. Like missing frames every now and then.
If I clean install a ROM the YT will work awhile normally but after few days and after installing some other apps the lagging starts again.
First I thought it was just the new F1xy kernel and reverted back to old fixy but problem remained. Then I tried Smoke kernel and problem remained.
Then I clean installed cDroid (new blobs) and everything was fine, for awhile. After installing Chrome, the lagging came back and I thought that Chrome was the problem and uninstalled it and videos worked awhile okey but then the lagging came again.
I've now tried several kernels and LOS14 (new blobs) and crDroid and installing and uninstalling YT and clearing its cache and whatnot rebooting and lagging always comes back sooner or later.
I used to run LOS14 with fixy or foxy and had no major issues with YT but now I just can't seem to shake this problem away.
I now run crDroid and SmokeR21.5 and with gaming or video-profile I might be able to watch some YT without lagging, but eventually it starts to jerk.
Does anyone else have this kind of lagging/jerking with YT and does anyone know how to get rid of it?

Now I haven't had any serious lagging for awhile and I have no idea why. I still run crDroid and SmokeR kernel. Bloody magic if you ask me...

---

And lags are back yet again. Every 10ish seconds roughly there is a slight jerk [emoji21]
I am using SmokeR kernel with gaming profile. Cpu freq doesn't dip under 696Mhz but still lags happen. Damn!

---

This might be a 1080p60 issue. At least yesterday I had no hiccups with normal 1080 video but 60fps one had occasional lags. Gonna try the new Smoke LOS14 next to see how that handles videos.

Have you tried Smoke LOS 14.1? Seems that YouTube issue is fixed there.

Great. Finally after so long, we might have ROM that YouTube don't sucks

Some results;
With Smoke LOS 14.1 I was able to watch 1080p60 videos without a hitch and without the performance app for few days iirc but after that videos started jerking so I installed the performance app and tried the with different profiles. Only with the Gaming profile I was able to watch 1080p60 videos without problems. So the Smoke LOS 14.1 is one solution for me.
Unfortunately that ROM is still too beta. Battery consumption and deep sleep behaviour is just bad and I would estimate that I could only get 4ish hours of SOT during few days cos of the battery drain.
So I decided to give crDroid 3.6 and F1xy 9.3 beta a go.
It seems that Youtube is having some mobile issues with 1080p60 videos and those are not available atm, 720p60 is the highest atm. I suppose they will fix that soon.
Anyway, crDroid + 9.3 worked like a charm for roughly 6 hours (minus the artifacts ofc). Then the jerks came back and Spectrum app didn't help at all. No matter what profile I used, I still got at least mild frame drops.
So I played with Kernel Auditor a bit and noticed that only settings that helped was if I set max and min CPU freq to the same value, e.g. 1800Mhz, all the YT videos play nicely. Even with 1000Mhz there was no huge frame drops. I am going to do some more testing but at this moment I speculate that the frame drops occur when CPU frequency fluctuates.
Has anyone else noticed anything like this? Am I the only one with these frame drops (lags, jerks, hitches) in 60FPS YT videos?

And after writing that message above 720p60 videos played just fine with Balanced profile without tinkering with frequencies. Idk what is going on with this tablet...

I think I found it what is causing the lags on youtube. I think it is the bloody Live Display setting and particularly its Night setting that is doing this.
I tried it few time to switch between Night and Off settings and with Night setting 720p60 videos lagged always and with Day or Off videos ran just fine with F1xy and Balanced profile.
I don't get it why changing a color temperature would cause something like this but at least I found a way to reproduce the issue.
So could someone else try and reproduce this issue:
1. Go to Settings --> Display --> LiveDisplay --> Display Mode --> Choose Night
2. Try some 1080p60 or 720p60 Youtube video.
3. If you get lags, change the LiveDisplay to Off or Day and try again.
Cheers.

What kind of lag you are getting? I've used LiveDisplay since day 1 and there is no lag annoying enough to me. I am using F2FS file system though. And horrible battery drain when screen off (1% per hour) with ForceDoze and Wi-Fi off.

Missing frames. Video jerks/skips. This can happen every 2 secs or every 10ish secs. Forcing CPU min and max freq to the same value fixed this as well when I tested.
I suppose it could be something else causing this but definitely LiveDisplay settings activate this (for me) when I tested my hypothesis few times yesterday.
There are different revisions of Mipad so this might not be issue for everyone.
And this also explains why usually after few days this always started happening to me when I flashed a new rom. I probably activated LiveDisplay after few days of use...

Yeah, it could be something specific for your MiPad or software set up.
Out of topic question, but do you experience same battery drain too when screen is off (around 1% per hour?)

---

I think this has to be a LOS14 issue cos I have had the same jerking in all highwaystar based roms and the new smoke LOS14. I just can't confirm now that if the LiveDisplay was the issue in those roms. But I bet it was cos I started using it not so long ago.

Naah mate. Atm I have pretty decent deep sleep behaviour. I am running crDroid 3.6 and Fixy 0.93beta iirc.

Ah, shoot. So we are talking about totally different thing. I had the impression that you are using LOS 14.1 Smoke, my bad. Personally I had no issue with LOS 14.1 for YouTube even using LiveDisplay. Just that annoying battery drain.
Btw, is there any bug for CrDroid (other than non working camera)? Because if turning LiveDisplay will give no lag YouTube, plus great sleep behavior I'd rather flash that instead.

I was using LOS14 Smoke just awhile ago but the nagging youtube lag appeared ( I presume cos I started using LiveDisplay) and yeah there was some weird deep sleep issues with that rom. Check pic.
crDroid is pretty much like any other off-shoot of highwaystars los14, so it has artifacts and no camera and you probably need to use custom kernel at some point. Atm i am going to stay on it until something with better battery optimization comes along.
And I am still not 100% sure that LiveDisplay is the ultimate cause of my YT lag. But I bet it has something to do with it cos it was so clear yesterday when changing to night mode --> YT lagged, turning it off --> YT no lags. But for now I'll keep using the mipad without the night mode and see what comes in my way...
