Running Fullscreen Video cause Stutter/lag in 19002

[MDM-1]

19002 introduced a horrible video lag (MPC-HC+madVR) in full-screen!
As soon as I go full-screen the fps drop sharply and stuttering begins, if I only go to the seek bar or right click menu etc. (thus still same resolution rendering), all works again in max fps (I have Fury GPU, that has more than enough strength for my madVR setting).
All worked in previous build (had the shutdown/restart issue though), same settings and all.

[#2]

@MDM-1I have the same issue too. Fullscreen video on all browser and fullscreen in videogame cause stutter and lag. There were nothing like this in the previous build i have. My GPU is AMD radeon vega 56. I tred updating my gpu driver but it didn't take effect.

[#3]

Yes I noticed on Feedback hub the game issues, and I presume they are all Shader relater (madVR uses them); but why only in fullscreen..?

Tried the driver too, no effect.
You also have AMD, does anyone with Nvidia (Intel iGPU) have the same issues?

I am limited to 10-15 FPS in fullscreen, and have near 75 FPS in windowed mode (my monitor is 75Hz Freesync).

Here is my Feedback link, please up vote if same/similar issue:

A new build is out, nothing is mentionned about our issue but it's worth trying it

[#6]

I installed it but issue is still there

[#7]

@MagicLinkUnfortunately, since it still isn't present in Known/Fixed issues, so not yet acknowledged as problem...

[#8]

Same here using AMD RX 580 with Adrenalin Driver 2019 19.9.3 in 19002 (32gb Ram, Ryzen 5 3600)
Video start lagging as soon as it goes fullscreen on chrome and firefox (youtube, steam), VLC, but not in potplayer (tested with AVC1 video codec and hardware acceleration).  

[#9]

If you are using the internal renderer in PotPlayer, sure, I have no lag in MPC-HC with "enhanced video renderer" that use CPU and not GPU (shaders).
If you used madVR in PotPlayer, you probably would have lag...

[#10]

Have you tried reinstalling your GPU driver properly or updating to a new one?

first uninstall it via DDU

Looks like a problem with mostly AMD cards?

I use VLC everyday and now I'm on build 19008, using Intel GPU 630 updated driver made for build 1909, things are fine. in VLC, hardware acceleration is set to automatic.

[#12]

Of course I first also tried to clean drivers (although I suspected it vas build fault - happened before) but no, this is a definitely a build problem, like many have it in games also. Not sure if AMD only issue, too little user info but in games they had NVidia too.

Like I said, not internal or hardver accelerated (like native etc.) options, ONLY variants with use of shaders, like madVR...

[#13]

Good info,
so either:
1. it is a bug and Microsoft should fix it
2. one of the Windows 10 components is changed or upgraded and Graphic card manufacturers need to release a compatible driver

[#14]

@HotCakeX I do think it is 1. 

If not, Graphic card manufacturers do not support insider, so in that case we are s*****d

[#15]

Well it's insider and it comes with its flaws. as you said it only effects shaders so not everything is effected.
there are currently bigger problems in insider than this. games with Battle Eye anticheat can't be run on insider Windows versions, they very popular games.

[#16]

@HotCakeX 

Updated drivers to latest version (19.10.2) after DDU uninstall and problem persists.
I disabled chrome hardware acceleration to be able to use netflix. I think this is an important issue.

[#17]

1. don't use Windows insider builds as your main OS.
2. the problem need a fix either from Graphic card manufacturers, specially AMD. i'm on Intel Graphic card with latest driver and everything is fine. so this is Not a universal problem of Windows 10 build 19008 insider.

[#18]

Ah, its finally acknowledged as "[ADDED] We’re investigating reports of frames being skipped, starting with Build 19002, when running games and videos fullscreen.".

Hope it gets fixed soon, as it is very annoying..

[#19]

That's good news ;)

[#20]

I have the same problem and noticed that it only happens when I open a video game/application/video in fullscreen on the main screen (when the checkbox "Make this my main display" is checked) and then the lag/stutter affects all screens.

[#21]

Have this problem as well with a Vega64@MDM-1 

[#22]

What's your graphic card?

[#23]

@HotCakeX I have an AMD RX480 8GB.

[#24]

Hmm AMD again

[#25]

I'm having the same issue with my GTX 1070ti. Any video or game for that matter stutters horrendously when running in Fullscreen. Windowed Fullscreens solves it in games that offer it, but it's pretty annoying.

[#26]

okay, open a feedback and add your details.

[#27]

@Dalto11 @MDM-1 @JEarly410 @Desperadov @MagicLink 

Fixed in build 19013. please update your Windows.

More info: https://blogs.windows.com/windowsexperience/2019/10/29/announcing-windows-10-insider-preview-build-1...

"We fixed an issue resulting in frames being skipped, starting with Build 19002, when running games and videos fullscreen."

[#28]

Yes it is fixed in build 19013.
Hope it newer comes back (but I doubt it, this IS Insider builds and the Fast one...).

[#29]

Yeah, though I think they are going towards stabilizing this build because 20H1 is actually going to be released in December 2019

[#30]

@HotCakeX same Problem here with GTX 1080 and also with 19013 ... Problems over Problems... I even cant go back to normal windows... deleted save-point

[#31]

EDIT:

working on "non-main-screen"

[#32]

You can always switch back to stable version of Windows
https://www.microsoft.com/en-us/software-download/windows10

[#33]

@HotCakeX I can't without completly reinstalling it... 

(Also my System crashes EVERY TIME I want to restart or shutdown.. even with shutdown -s -t 0)

so clean install it, no big deal.

obviously insider version is not for you and you need stable Windows instead.

[#35]

It actually is kinda big deal... I installes so many Programs, they cant be used without reinstalling it.. (It's a regedit thing I guess) It would take me DAYS to get back to normal... Do you know, if it can reverted if the next normal Windows Update occurs? Or should I wait till there's maybe a fix withi the next Insider-Updates?

In fact I wanted to use the Insider Feature within "Your Phone" to call with people with my Android while using my PC-Headset...

Not all people can handle Windows insider versions as their main everyday OS, and Microsoft warns users before installing it.

the problem that you are talking about was solved weeks ago. it's build 19013 now

https://blogs.windows.com/blog/tag/windows-insider-program/

You can also get individual builds from here and make your own ISO file to do an in-place upgrade:

https://uupdump.ml/known.php

but with the problem you are having, I don't think you can pull that off and only choice is a fresh install.

[#37]

@Mr_R341The issues you are having are different, because the ones we talk about here (and the old shutdown /restart one) have been solved.
You must investigate, and I recommend you to open a new thread, and before that check for other issues and especially causes!

[#38]

like I said... I'm on the latest Insider-Build and the Problem still occurs in 19013...

[#39]

@Mr_R341And like I am saying it is solved for everyone except you, so something went wrong in your case, thus a different problem.

Where and how, was the update to 19013 uncomplete or faulty (not unheard of, and seems to me to be your case) or something third... Only you can know/test.

For example IF you updated to latest build AFTER having System crashes etc., you basically transferred an corrupted system/files/registry; it is a big no-no, in that case you restore or go back to previously good version and update, etc. It is practically essential to have backups if on insider and especially on "fast".

[#40]

I even can't keep anything if I want to reinstall windows O.o

I can keep apps and data with the latest insider build... well.. lets see if I can "refresh" and repair the system this way....

[#41]

Of course you can.

before doing that, moving all your Important files from your C drive to other drives, you can also put them on OneDrive if you have enough space there.

[#42]

I think he meant program data, since he already mentioned it, not personal files...

[#43]

Doesn't matter,
Windows insider is not for everyone to use as their main everyday OS. they need to dual boot with a stable one

[#44]

@HotCakeX No I meant personal files + Apps.... 
All I can choose is 

"Keep nothing"

[#45]

You can manually move personal files from your C drive to other drives.

[#46]

Yup... after buying another 6TB HDD

[#47]

Why? your C drive is 6TB?

[#48]

Yes... I thought: Partitioning will do...
But Windows once thought: "Nope.. I don't care about partitioning.. I don't even ask on wich partition I'll be installed.. I just wipe everything"
Know that, becouse already had that... took me whole 2 Years to recover from my Data-Loss..

Is it possible to unregister from Insider and just wait for the next big update?

you need to take your computer to a professional to do the partitioning for you.

[#50]

@HotCakeX Whats in your mind? What shoukd he do? I meant with the partitioning.. I'm really sure I'm able to do this as well... Just tell me what you think about it... How  should I partitioning it?

Also it has to be possible to trick windows that it thinks the normal version is a new update instead of an old version...

"Your Data, Apps and Settings can't be keep, couse the actual Version of Windows probably is installed in an unsupported location or you try to install an old Version of Windows"

I'm really sorry :D But I'm struggeling very hard here...

Also: I tried to reinstall the Insider Build and it worked well, but the Greenscreen still occurs so as the stuttering in fullscreen on "Main-Screen"

 
And with simply uncheck the Box and waiting for another normal Windows Update will work to get to normal?
