Youtube stutters after switching to AMD

L00P · September 12, 2023, 7:23pm

After I made the switch to AMD youtube video playback is very choppy. I followed the Arch wiki and have the fiollowing packages installed:

▶ pacman -Q | grep -E "(amd|radeon|mesa|vulkan)"                                                                                                          0 6ms
libva-mesa-driver 1:23.1.7-1
mesa 1:23.1.7-1
mesa-utils 9.0.0-2
mesa-vdpau 1:23.1.7-1
radeontop 1.4-2
vulkan-headers 1:1.3.264-2
vulkan-icd-loader 1.3.263-1
vulkan-mesa-layers 1:23.1.7-1
vulkan-radeon 1:23.1.7-1
xf86-video-amdgpu 23.0.0-1

Here is my inxi -G:

▶ inxi -G
Graphics:

I already tried resetting my firefox installation by removing the .mozilla dir but the issue won’t resolve. Media.ffmpeg.vaapi.enabled is set to true and in about:support the compositing is set to webrenderer.

Playback is smooth on a chromium based browser. Any ideas?

Have you tried setting these in about:config?

media.ffmpeg.vaapi.enabled set to true
media.ffvpx.enabled set to false.
media.rdd-vpx.enabled set to false.

I already had the first one set to true and toggled the latter 2 options to false.

The choppiness is no longer there. I’ll continue testing and hope the stuttering won’t rear it’s ugly head again. Thank you @dalto!

Today when the problem occurred again, extreme choppy yt playback. I let a video play and checked if all the values in about:config where still present which they were then the whole desktop crashed and I landed in the login screen.

Here is the output of dmesg | grep amdgpu

After the crash youtube playback was smooth again. I decided to reboot the system and the exact same thing happened, system crashed when playing a yt video and after logging in video playback was smooth.

Is this a driver issue or could it be a hardware issue?

My system is up to date and I’m running the the latest linux kernel.
