Maybe you're not getting hardware acceleration. Please attach (as opposed to paste) the output of LIBGL_DEBUG=verbose glxgears 2>&1 Created attachment 10886 [details]

Looks fine... can you try isolating the problem with git-bisect? I will give a try this weekend. OK, the problem is that the latest Intel driver disables Tiling on i915 (due to XV corruption and lockup). Disabled tiling of depth and back buffers causes terrible slow down. So this bug can be closed. Mass version move, cvs -> git |
