It is now 2 weeks I run linux-image-current-meson64 with no problems.
I manage to get rid of tearing while playing video with vlc by using wayland/weston instead of X11/openbox (picom did not help).
While playing video cpu goes from around 40% in X11 to 20% with weston \o/.
You can find vlcd.service, scripts and config files in attached files.
TODO list :
- Move vlcd.service to weston.service and try to replace vlc-xxxx.sh scripts with ~/.config/systemd/vlcd
