Is there a way to make video playback smooth and use hardware acceleration on Linux Mint? Chrome works fine.

BeOS

Almost all important hardware acceleration features are disabled. I can't play 3 YouTube videos side-by-side in even 720p without massive frame drops.

Here are my system details:

Graphics Feature Status
Canvas: Software only, hardware acceleration unavailable
Compositing: Software only. Hardware acceleration disabled
Multiple Raster Threads: Enabled
Out-of-process Rasterization: Disabled
OpenGL: Disabled
Rasterization: Software only. Hardware acceleration disabled
Skia Renderer: Enabled
Video Decode: Software only. Hardware acceleration disabled
Vulkan: Disabled
WebGL: Software only, hardware acceleration unavailable
WebGL2: Software only, hardware acceleration unavailable
Problems Detected
Accelerated video decode has been disabled, either via blocklist, about:flags or the command line.
Disabled Features: video_decode
Gpu compositing has been disabled, either via blocklist, about:flags or the command line. The browser will fall back to software compositing and hardware acceleration will be unavailable.
Disabled Features: gpu_compositing

@beos Missing Hardware Acceleration causes slowness.

Open Settings → Webpages and set "Use of Hardware Acceleration" to active, restart Vivaldi.

DoctorG

@beos I do not run Linux Mint (only Manjaro, Debian & Ubuntu on NVidia) and can not tell much. Perhaps a Mint user knows a solution.

Please check Troubleshooting issues.

After you checked all items and that did not solve your issue, tell us more:

@doctorg That option does not exist.

Thanks! Disabling #ignore-gpu-blocklist fixed it.
