High cpu usage while watching youtube videos

Abhimanyu

I think the problem is due to the lack of browser's ability to hardware-accelerated video decoding although i don't know much about its technical aspect. I tried to follow the solution listed here but that didn't help.
Please help in fixing this
using linux mint 20.2 on i3 3110m processor

Hi, if you use Vivaldi from the official download page or repro you don´t need any Flags, except your GPU is no longer supported from Chromium 92.
Check if hardware acceleration is enabled in: vivaldi://settings/webpages/

hi, tried it as per your suggestion. It was enabled but that didn't fix the issue.

Hi, I need to enable:

Override software rendering list
Overrides the built-in software rendering list and enables GPU-acceleration on unsupported system configurations. – Mac, Windows, Linux, Chrome OS, Android

#ignore-gpu-blocklist

Enabled
GPU rasterization
Use GPU to rasterize web content. – Mac, Windows, Linux, Chrome OS, Android

#enable-gpu-rasterization

Enabled
Hardware-accelerated video decode
Hardware-accelerated video decode where available. – Linux

#enable-accelerated-video-decode

for my old Quadro K1100m, for my desktop RTX 2060 all flags are default.

Check Graphics Feature Status with: vivaldi//gpu

@mib2berlin tried this one too, the first 2 options get enabled but the 3rd flag isn't there in the list.

Ah , I am sorry, the last one is an old flag and I have to enable:

#temporary-unexpire-flags-m90
#temporary-unexpire-flags-m91

for the stable build, I use the snapshot for daily work.
I guess the last Chromium update remove the flag.
No idea what we do if the developer really remove this.
