SDDM Wayland log

SUMMARY

Unlike the window of Firefox with GPU accelerated Webrender, the native OpenGL Wayland window of mpv just stays black.

STEPS TO REPRODUCE
1. Open any video in mpv with native OpenGL Wayland (should be the default setting) on Nvidia Wayland session.


OBSERVED RESULT

Window just stays black. It works with AMD & Intel with KWin Wayland GBM.


EXPECTED RESULT

It probably should also work with mpv on Nvidia when Firefox does so.

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Linux 5.13.14
KDE Plasma Version: 5.22.5
KDE Frameworks Version: 5.85
Qt Version: 5.15.2

ADDITIONAL INFORMATION
Happens on both 465 and 470 Nvidia driver and with mpv 0.33.1 from Arch repo or latest git-master build.

This is Nvidias fault. You will get the same problem with Gnome and any other compositor running Nvidia Wayland.

To use native Wayland mpv you have to use gpu-context=wayland vo=gpu hwdec=nvdec opengl-es=yes
