Youtube is not fully 'watchable' on firefox but feels significantly better. I can also now watch full screen youtube videos on chromium 1920x1080 with no stutter (lenovo g50-70). Generally gnome 3 feels a bit snappier especially on first load, bringing up the menu searching for 'terminal' leads to a faster rendering of the results. This might be just 'imagined' by me. On a more measurable front. I ran the octane benchmark against firefox post and before the patch. It resulted in a slight improvement from 12486 to 12826 score [1]. cpu0: Intel(R) Core(TM) i7-4510U CPU @ 2.00GHz, 1895.93 MHz cpu1: Intel(R) Core(TM) i7-4510U CPU @ 2.00GHz, 1895.62 MHz cpu2: Intel(R) Core(TM) i7-4510U CPU @ 2.00GHz, 1895.62 MHz cpu3: Intel(R) Core(TM) i7-4510U CPU @ 2.00GHz, 1895.62 MHz inteldrm0 at pci0 dev 2 function 0 "Intel HD Graphics" rev 0x0b running Intel Haswell Mobile for the gfx card.
