[SOLVED] Full screen flash video tearing - intel sna acceleration

Hi,

Using the following hardware and packages below:

EndSection

I´m experiencing the following:

I have disabled the discrete GPU using vgaswitcheroo and I'm using KDE (with OpenGL desktop effects & vsync) as my main desktop.
When watching full screen flash videos, there's noticable tearing. Switching to uxa acceleration doesn't make any difference, neither does disabling flash hardware acceleration in /etc/adobe/mms.cfg.

The only thing that seems to help funnily enough, is disabling vsync in KDE, which doesn't make any sense to me.
I have no issues watching any other type of video, this seems related to Flash videos only.

I'd like to know if anybody else, with a similar setup, is also experiencing this kind of behaviour.

Re: [SOLVED] Full screen flash video tearing - intel sna acceleration

Experiencing tearing with vsync in general is a common thing. Any reason you must have it on?

Re: [SOLVED] Full screen flash video tearing - intel sna acceleration

And I thought having vsync enabled should minimize tearing...I guess I was wrong. No reason to have it enabled, no. I'm wondering if KDE enables it by default since I can't remember switching it on.

Re: [SOLVED] Full screen flash video tearing - intel sna acceleration

In Mageia KDE, I have to have vsync turned on to eliminate tearing.  For Arch, I am using XFCE with compiz.  This is on a ThinkPad X220 with Intel HD3000 graphics.

Tried full screen flash with the default uxa and also with sna.  Both run virtually free of tearing on a youtube video that I use for a test (I set the quality to 480p and run fullscreen).

EDIT:  Just booted Mageia KDE.  I see I have desktop effects turned on, using VSync, using OpenGL 2 Shaders, using OpenGL compositing.

EDIT2:  Yes, I see that just as you report regarding KDE (Mageia 2 here), I have tearing on viewing flash videos in my browser, but no tearing viewing the same video with VLC.  This is not the case using XFCE with compiz (no tearing).  Same laptop in both cases.

Re: [SOLVED] Full screen flash video tearing - intel sna acceleration

Hi,

When I disable vsync in KDE I have quite some tearing when moving Dolphin windows, for example.

I have compared your setup to mine, and it is the same. Laptop is different though, this one is a Vaio VPCSB36FG.

Cheers,

Eric

Re: [SOLVED] Full screen flash video tearing - intel sna acceleration

VSync should be turned on.

Experimenting a little more in Mageia 2 KDE, I find that checking the box: Desktop Effects > Advanced > Suspend desktop effects for fullscreen windows - makes an improvement for full screen flash videos.  It's still not quite as smooth as Arch XFCE w/compiz, but it's not bad.

Re: [SOLVED] Full screen flash video tearing - intel sna acceleration

Hi David,

Checking that box doesn't seem to have that much effect on my Arch KDE setup, but thank you for the suggestion anyway.
By the way, this is the video I'm using to test various options:

vsync's function is to *eliminate* tearing.

Re: [SOLVED] Full screen flash video tearing - intel sna acceleration

I went back to Desktop Effects > Advanced.  Now I am using the following settings:

Compositing type: OpenGL
Keep window thumbnails: Only for Shown Windows
Scale method: Accurate
unchecked - Suspend desktop effects for fullscreen windows
unchecked - Use OpenGL 2 Shaders
checked - Use VSync

Seems to be no tearing now.  I believe unchecking "Use OpenGL 2 Shaders" was the key.

Yes! Disabling the 'OpenGL 2 shaders' did the trick! Thank you, marking as solved.

Re: [SOLVED] Full screen flash video tearing - intel sna acceleration

Using the following components the default KDE settings can be maintained and tearing has disappeared altogether (only tested in Firefox 15 so far):

local/flashplugin 11.2.202.238-1
local/intel-dri 8.0.4-2
local/libva-driver-intel 1.0.18-1
local/xf86-video-intel 2.20.5-1 (xorg-drivers xorg)

p.s. sna acceleration is _enabled_

Re: [SOLVED] Full screen flash video tearing - intel sna acceleration

When I try to disable 'OpenGL 2 shaders' I get an error saying that desktop effects can't be started with the configured options and it just reverts to having them enabled. Did this happen to anyone else? (Maybe I have a problematic combo but... what exactly...?)

Why are you using Intel rendering when you have an AMD GPU? I might be mistaken but Ivy/Sandy bridge should not work with AMD GPUs?
