I'm guessing this might be related to the fact I'm running on an Intel graphics desktop. So the buffer implementation for the EGL clients is still GBM. However the buffer implementation for the software clients is just local memory (ShmBuffer).
** Summary changed: - Software compositing of EGL clients is much slower than software clients + Software compositing of EGL clients is much slower than software compositing of software clients -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to mesa in Ubuntu. https://bugs.launchpad.net/bugs/1576032 Title: Software compositing of EGL clients is much slower than software compositing of software clients Status in Mir: New Status in mesa package in Ubuntu: New Status in mir package in Ubuntu: New Bug description: Software compositing of EGL clients is much slower than software clients. Even when the EGL client is allowed to render in hardware. There is something weirdly slow about our EGL texture binding compared to software textures... Start the server with software rendering: $ sudo env GBM_ALWAYS_SOFTWARE=1 mir_proving_server --compositor-report=log Now start a fullscreen client (even with hardware rendering enabled) and drag the window around (so it's no longer bypassed). Compositor performance: 7 FPS with mir_demo_client_eglflash (rendered in hardware, only rendering 1 FPS) 7 FPS with mir_demo_client_egltriangle (rendered in hardware) 30 FPS with mir_demo_client_fingerpaint (not redrawing at all) 30 FPS with 'mir_demo_client_progressbar 1' (rendered in software at 1 FPS) 30 FPS with 'mir_demo_client_progressbar 60' (rendered in software at 60 FPS) 30 FPS with 'mir_demo_client_flicker' (rendered in software at 60 FPS) To manage notifications about this bug go to: https://bugs.launchpad.net/mir/+bug/1576032/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
