Firefox Version 141.0a1 (nightly) Build ID 20250613093648 (up to date) You need to set gfx.wayland.hdr=enabled in Firefox about:config. And you have to run it with HDR mode enabled >From the issue on Mozilla's bug tracker > From Firefox perspective HDR is not enabled (missing support for DRM 30313050 > format ( VA_FOURCC_P010)) It still crashes, although there is a patch for Disable direct HDR rendering if Wayland compositor is missing support for YUV formats https://phabricator.services.mozilla.com/D253312 Maybe it did not land to nightly yet... So... I've filed the bug that KWin is missing support of HDR formats and modifiers from Firefox's view when HDR is enabled > iface_zwp_linux_buffer_params_v1 extension doesn't advertise dmabuf YUV P010 > format used for HDR rendering Thank you -- You are receiving this mail because: You are watching all bug changes.
