Flash video tearing.

platnumX · 2009-07-12 06:14:13

when ever i watch a flash video on youtube or other such sites, there is horrible screen tear on the video when ever something moves in the video, I have provided necessary info about my setup below.

WM=Compiz, but I have tried with metacity and kwin, same problem.

Graphics card=nvidia 8600 gt

DE=gnome

flash ver.=10,HW acceleration enabled, tried disabling, didn't help.

Can anyone provide a solution?

Which driver do you use? Is it a new problem by you or have this ever worked in the right way?

platnumX · 2009-07-12 07:52:10

i use the official nvidia driver, and I don't remember when the problem started.

Hello everybody,

I had the same problem and solved it using compiz via compiz-manager. I am using XFCE4 + Compiz/Emerald. Here is my solution:

In "Compiz-Config/DisplaySettings" I activated "sync to vblank" and set the output resolution to the native resolution of my screen. I also set the refresh rate to 60hz (for my TFT screen).
In "CompizConfig/Workaround" I activated "Force Synchronisation between X and GLX".
In "Nvidia-X-Server-Settings/X-Video-Setting" I set "sync to vblank" for "video texture adaptor" and "video bitter adaptor". The "X-Server Display Configuration" is set to "auto".

My xorg.conf looks like this (using evdev device detection):

Section "Device"
Identifier "Device0"
Driver "nvidia"
VendorName "NVIDIA Corporation"
BoardName "GeForce 7600 GS"
EndSection

I had the same issue and found all those work arounds... but there is and will always be a flash fullscreen issue we need that to be fixed! lol

Maybe fullscreen videotearing is another problem but I do not have any video tearing problems. I am using Mozilla Firefox and VLC.

How about flash for linux sucks problem, ask any user and they can point any of the following problems: cpu hog, crashing with some sites, video tearing (your problem).

I would bet it doesn't even try to make use of XV and the algorithms it uses to decode video must be very poorly optimized, complain on the adobe forums, maybe the squeaky wheel approach will help solve the problem.

I found by accident that flash fullscreen works beautifully on my system after disabling compositing effects in kde 4.3. I'm glad there's a plasmoid called "toggle compositing". YMMV

I checked my CPU load (Intel Core 2 Duo 6300 @ 1,86Ghz) while running a flash video with Mozilla Firefox: embedded: 40% / fullscreen 80%. No video tearing no jagging.
Same video with VLC: 40% (fullscreen AND window-mode). Also no video tearing and no jagging.
But I have to admit that the CPU loads are too high with Firefox in fullscreen-mode.

Firefox (3.5.6-1) never crashed on my system, except once. I had approximately 30 tabs open (most of them with flash content). And I was playing some flash music videos. Previous versions of Firefox weren't that stable, but i can't remember which version.
I am using flashplugin 10.0.42.34-1 and swfdec 0.8.4-1.

Not all flash pages crash for me though, the cpu in my notebook does have the lahf instruction and I'm using the lahf fix and it still crashes with some pages go figure (the top gear page terrible in that, every time I close the tab with the video firefox just closes).

Funny - the same thing helped in my case in XFCE.
So is that compositing that generates the issue, or just flash cannot cope with the compositing?

when in doubt, blame flash.

from my understanding, flash uses it's own doo-hickey to do video, instead of going through whatever X/DE is providing, so they conflict. I didnt really have a lot of problems in kde 3.5 (other than the tearing in fullscreen), but kde 4.3 wont even let it go fullscreen unless compositing is off.

fullscreen started working with composite on today. I'm not sure why, but I was working on a related issue to plasma desktop in kde 4.3 and now fullscreen video playback works.
