Similar bug: https://bugs.freedesktop.org/show_bug.cgi?id=93263. Fedora 22 packages: kernel-4.4.13-200.fc22.i686 xorg-x11-server-common-1.17.4-1.fc22.i686 xorg-x11-drv-intel-2.99.917-15.20150729.fc22.i686 Adding to xorg.conf Section "Device" Identifier "igfx" Option "DRI" "2" EndSection should fix the gnome-shell issue (due to fedora's settings). Looks like mesa + dri3 is inoperable on 945gm. Similarly look at disabling "hardware acceleration" in firefox? Not sure what firefox is doing with youtube, but if it is suffering from GL swrast that will help.

I noticed that 720p videos run quite poorly even on F22 but your config snippet helps with greatly with Totem. With DRI3 (the F24 default) glamor can't be enabled and gstreamer renders via slow swrast. Hello Michal, it seem so that this bug has been neglected wayyyyy too long, I apologize that. Can you please retest with the latest kernel (preferable from drm-tip) and X-components, and change status to REOPENED if problem still persist. Chris - is the component (DRM/Intel) right place for this? You said in comment 5 that " mesa + dri3 is inoperable on 945gm." As far as I know, this is just a mesa bug. I left it here as I don't know what gave the impression that the kernel was a critical factor in the bug. Created attachment 131005 [details]

Running Fedora 25 with all updates and the original problem with high utilisation after login is gone (DRI2 seems to be enable by default in Wayland) but YouTube video playback performance in Firefox is still the same, barely plays 360p.
kernel-4.10.10-200.fc25.i686
mesa 13.0.4-3.fc25.i686
wayland 1.12.0-1.fc25.i686
Just for the record: I don't use the system any more, just for testing from time to time.
Chris should this bug be moved to Mesa? this issue seems to be out side of the i915 and should be more involved with Mesa. Closing issue also for the lack of response... The beauty of having a unified bug tracker is that if you think there is no kernel aspect to the bug, you can just reassign it to the mesa component. And vice versa. -- GitLab Migration Automatic Message -- This bug has been migrated to freedesktop.org's GitLab instance and has been closed from further activity.
