Hardware Acceleration

When there's movement in the video it starts to look like its behind a cracked glass, it's not as serious visually as my comparison makes it seem but when there's alot of movement it becomes really bad. I installed vaapi package (libva-intel-driver) and tried it out in mpv (hwdec=vaapi - ctrl+h at runtime) which made the "crack" much more pronounced across the whole screen (1 constant line)
vainfo output:

vainfo: VA-API version: 1.9 (libva 2.9.1)
vainfo: Driver version: Intel i965 driver for Intel(R) Sandybridge Mobile - 2.4.1
vainfo: Supported profile and entrypoints
      VAProfileMPEG2Simple            : VAEntrypointVLD
      VAProfileMPEG2Main              : VAEntrypointVLD
      VAProfileH264ConstrainedBaseline: VAEntrypointVLD
      VAProfileH264ConstrainedBaseline: VAEntrypointEncSlice
      VAProfileH264Main               : VAEntrypointVLD
      VAProfileH264Main               : VAEntrypointEncSlice
      VAProfileH264High               : VAEntrypointVLD
      VAProfileH264High               : VAEntrypointEncSlice
      VAProfileH264StereoHigh         : VAEntrypointVLD
      VAProfileVC1Simple              : VAEntrypointVLD
      VAProfileVC1Main                : VAEntrypointVLD
      VAProfileVC1Advanced            : VAEntrypointVLD
      VAProfileNone                   : VAEntrypointVideoProc

Also, searched and codecs  listed on the wiki are installed (suspected lack of some to be a problem)
This is my first time with linux so I don't if it's an incompatibility with hardware on linux, but the problem didn't exist on windows for sure.

Re: Hardware Acceleration

Please edit your post and chose a meaningful subject line.

Then see https://wiki.archlinux.org/index.php/In … cs#Tearing

mpv -vo=gpu --video-sync=display-resample maybeporn.mp4

Also a compositor (picom or part of your DE) can impact this.

Last but not least: if this is a dual-GPU system (optimus), things can get more complicated depending on the actual configuration (which you'll have to elaborate on)
