[ Daniel van Vugt ]
* Cherry-pick 2 patches for stuttering fixes
* Avoid cursor stuttering over some windows (LP: #2023766). This will also
improve best-case input latency by roughly half a frame.
* Avoid render stuttering in some fullscreen games (LP: #2016990).
* Update Support-Dynamic-triple-double-buffering.patch
* Fix a failure to resume from sleep (frozen black screen), which seems
to be an old bug but only became likely in 44.1.
* Fix a crash on resume from sleep (LP: #2020049).

Bug description:
[ Impact ]
Mouse cursor stutters but only over GUI elements that are animated.
[ Test Plan ]
1. Open Settings.
2. Move the cursor up/down over an empty area of the desktop.
3. Move the cursor up/down over the list pane on the left side of the
Settings window.
Expect: No difference in cursor smoothness whether the window below is
animating in response to movement or not.
[ Where problems could occur ]
In frame scheduling, so the risk is more stuttering or screen freezes.
[ Workaround ]
Add this to /etc/environment:
CLUTTER_PAINT=disable-dynamic-max-render-time
