This means = that there is a LOT of data copying going on between Firefox and X.org.=20 What window resolution, video resolution, whether fullscreen or not? Better open a new bug and try various rendering toggles: - run a compositing manager (e.g., x11-wm/compton) - x11 driver (i915 vs. generic kms vs. vesa) or its options - gfx.xrender.enabled -> false - gfx.canvas.azure.backends -> skia - gfx.content.azure.backends -> skia (maybe buggy) - layers.offmainthreadcomposition.enabled -> false - layers.acceleration.force-enabled -> true (uses OpenGL) - BUNDLED_CAIRO -> off - GTK2 vs. GTK3 Firefox doesn't offload video decoding/scaling via VAAPI/XVideo unlike mpv/mplayer yet. However, OpenGL layers are scaled on hardware if available. --=20 You are receiving this mail because: You are the assignee for the bug.=
