[SOLVED] Screen tearing in chromium netflix

Daedra · 03-10-2016, 10:41 PM

I am using Alien Bob's chromium package to watch netflix. Everything is working fine but I am getting really bad horizontal screen tearing. I have tested in KDE/Mate/Mate-Compiz/Xfce and I get tearing in all off them. I am thinking this is possibly an nvidia driver issue. I am going to uninstall my nvidia driver and try with nouveau but I just wanted to see if anyone else is having this issue or has any hints on how to fix it?

Enable v-sync that will eliminate tearing.

Save the following as /usr/share/X11/xorg.conf.d/10-tearingfix.conf:

Code:

Section "Screen"
        Identifier      "nvidia"
            Option         "metamodes" "nvidia-auto-select +0+0 { ForceFullCompositionPipeline = On }"

        Option          "TripleBuffer"                  "on"
        Option          "AllowIndirectGLXProtocol"      "off"
EndSection

Thanks for the replies. I finally figured it out. I had to dig a little deeper in my google searching but I found these pages that lead me to the answer.

It turns out that hardware acceleration was disabled even though it was enabled in settings. Launching chromium from the command line with --disable-gpu-sandbox and enabling "Override software rendering list" in chrome://flags enabled hardware acceleration and fixed the tearing. Chromium did give me a warning about unsupported option and possible instability but so far it is working fine.

Daedra, THANK YOU! You've allowed me to get rid of the performance-killing "solutions" that I've been using.

I set the following to make it permanent:

Code:

export CHROMIUM_USER_FLAGS=" --disable-gpu-sandbox "

The CHROMIUM_USER_FLAGS overrule every setting made in /etc/chromium so that is kind of a last resort - for instance your Flash plugin will no longer work.
It's more elegant to create a new file in /etc/chromium and have the filename end in ".conf".
Inside you put:

Code:

CHROMIUM_FLAGS="$CHROMIUM_FLAGS  --disable-gpu-sandbox"

Yeah that is better. Thanks Eric and Dugan.
