This first error is not Atom-specific but also happens on a Haswell i7-4770 desktop:
intel_miptree_blit: Can't use hardware blitter from MESA_FORMAT_R8G8B8A8_UNORM to MESA_FORMAT_A_UNORM8, falling back. intelCopyTexSubImage - fallback to swrast I'll move that one to a separate bug. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to unity8 in Ubuntu. https://bugs.launchpad.net/bugs/1580792 Title: Unity8 on Intel Atoms performs poorly Status in unity8 package in Ubuntu: Confirmed Bug description: (problem forked from bug 1549455) Unity8 on Intel Pineview performs very poorly. Frame times appears to be up to 900ms, Qt's renderer thread using 100% CPU. Running unity8 with MESA_DEBUG=1 EGL_LOG_LEVEL=debug reveals a few MESA errors: http://paste.ubuntu.com/16344427/ Quoting @vanvugt "Those Mesa errors "Mesa: User error:" all look like OpenGL features that Unity8 is hitting but mir-demos don't. So those gl calls are also good candidates for explaining poor performance, especially if Mesa is falling back to software rendering for them." Since Qt tends to perform just fine on that hardware in X11, something isn't right.
