Horizontal Screen Tearing on youtube videos

[Scrazeloppe]

I am using latest version of chrome ( 40.0.2214.94 m)(Or whatever is now the latest) Whenever I watch a youtube video and the camera moves upwards, there is a horizontal line that is tearing. Just one of them, my gpu is ATI Radeon HD 4300/4500 Series. Os is Windows 7 ultimate. I have adobe flash player installed adobe flash player 16 NPAPI.

if you have the Aero theme running, pleas disable that and tell me if it persists. (Ive been seeing some vertical tearing with QHD displays under aero enabled)

conversely if its off, then your screen tearing because you don't have vertical synchronization. you can enable this in drivers. flash draws directly to the screen in most situations so you will have to set vsync to the flash process. (or just enable the aero theme, and it will handle the screen buffer for you)

With the new updates to youtube my browser uses HTML5 now for videos, where can I enable vsync in drivers?

you should enable it for the browser then.
However, i lack any AMD graphics hardware to be able to give a guide on changing driver settings for it.

taking a guess at it though...
you should be able to add Chrome to the 3D settings page and force vsync on like you would with a game. (this is how it works for Nvidia) from there, apply, and close out chrome. when you relaunch it, it should never render any more than 60fps if oyu have a 60hz display and tearing should be gone.

Can't seem to find it.

i checked a view and it seems its an all or nothing with ATI/AMD GPU's rather than a per application thing, unless you use some third party software... i cant grantee anything about this post, but its marked as the solution on tom's guide so maybe it will be helpful. http://www.tomsguide.com/answers/id-1728320/catalyst-control-center.html

it also seems this behavior in Chrome has been around for a while too.

Ive found guides claiming you can disable the Vsync option, however the flag they are toggling seems to no longer be available in current builds of the browser.


i am sorry that i am unable to provide a known working solution.

It's alright, I can just wait someone else may have a solution. Thank you for your help tho

games and videos in media player work fine but online video is tearing. fullscreen/cinema mode/normal mode all are tearing.

im on an i7 with google chrome and nvidia gtx650. monitor is samsung 27inch curved.

ive tried all the vsync options in nvidia, does nothing 🙁
ive tried changing hardware acceleration in the browser, does nothing 🙁
all drivers/flash/html5 etc are all updated and working fine.
ive tried various settings/fixes in chrome://flags/ and chrome://GPU. with the log message "GpuProcessHostUIShim: The GPU process exited normally. Everything is okay" .still nothing fixes the tearing 🙁
ive even tried different vga and hdmi cables all brand new. still no luck

very frustrated now 🙁 nothing so far has worked and im out of ideas

For those who have this issue and find this thread through googling, but are on Windows 10 like I am and can't use the Aero theme, this is the solution:

I'm running the latest build of Windows 10, EVGA GTX 970 SC, running on Nvidia 368.22. I'm running HDMI out of my PC into a Vizio E55-C1 HDTV (60hz refresh rate).

A week or so ago, I started getting massive horizontal screen tearing in chrome while watching full screen videos. It happened in Youtube, Netflix, and MLB.tv. When I went full screen in Firefox the tearing wasn't there, but I much prefer to use chrome.

I googled for hours on the subject and the big fix everyone talked about was using the Aero theme in Windows 7. Doesn't help me - I'm on Windows 10.

I tried mucking around with the refresh rate on the HDTV, didn't work. I went into the Nvidia Control Panel and set the Chrome 3d application Vsync setting to "adaptive (half refresh rate)" as I had seen that as an answer while googling. It worked up to a point... but the playback wasn't nearly as smooth as before.

I'll just get to the point and say that I found the solution. The solution is to go to chrome://flags and DISABLE "Smooth Scrolling". I did that - all full screen tearing problems instantly fixed.

I wish I knew where to post this so that more people could find it - it was a bitch trying to find the solution and anyone who's run into the same problem knows how annoying it is. Hope this helps someone else with the same issue.
