           Summary: Issue: Firefox Crashes When Playing HDR Video with
                    Wayland HDR Enabled on KDE
    Classification: I don't know
           Product: kde
      Version First unspecified
       Reported In:
          Platform: Other
                OS: Linux
            Status: REPORTED

When using Firefox on KDE Plasma with gfx.wayland.hdr enabled, attempting to
play HDR video content causes Firefox to crash. The crash occurs because KDE's
Wayland compositor doesn't properly support the YUV format (specifically P010)
needed for HDR video rendering.
Technical Details

    The crash happens immediately when trying to play HDR video content
    Firefox attempts to use dmabuf with YUV P010 format (fourcc 30313050) for
HDR rendering
    KDE's Wayland compositor rejects the buffer with error: "importing the
supplied dmabufs failed"
    The specific error occurs with zwp_linux_buffer_params_v1 when Firefox
tries to create a buffer with an unsupported format/modifier combination

Error Message

wl_display#1.error(zwp_linux_buffer_params_v1#80, 7, "importing the supplied
dmabufs failed")

Reproduction Steps

    Enable gfx.wayland.hdr in Firefox
    Open an HDR video file (or HDR content from a website)
    Firefox crashes during video initialization

>From mozilla
```
iface_zwp_linux_buffer_params_v1 extension doesn't advertise dmabuf YUV P010
format used for HDR rendering so we see the crash here. If you believe it's a
bug you need to report it at KDE bug tracker / KWin component. From application
perspective HDR is not supported. You can also try MPV in HDR mode to test it.
