Texture from pixmap is enabled. you said it was nvidia? it's intel? or this is a different machine? intel can't do partial render. even though intel were behind the buffer age extension, their drivers don't support it. nvidia do. :) you can reduce the cutout limit with an env var set before e runs: export EVAS_GL_CUTOUT_MAX=100 for example (the default is 512). reduce it as desired > http://git.toanpham.com/archive/e19_cpu.mkv > > > > Here is the result of "perf top" while glxgears and firefox are running. > As you can see the top offender is libevas.
