Disabled Aero. Made little difference. Only thing that fixes it on the Cubes capx is WebGL 0 fullscren 0. Does not work on other games i try, apart from Space Blaster which appears almost always stutter free somehow(could be my eyes).
The problem also appears on Android 4.0.3, both wrapped via CocoonJS and on browser(Chrome Beta and latest Stable release), with or without WebGL. This leads me to believe it's something either in HTML5 or Construct 2 that makes things go out of sync every now and then.
The i7-2670QM laptop where it ran perfectly had Aero with all the gizmos enabled.
I have the newest drivers on all machines. Even reinstalled them to confirm it's not them.
A newer Android version could help it, but the fact that almost 60% of android users use 4.0 and below doesn't help me with that.
EDIT : Tried many things - Older Construct versions, different ways of making the motion(both dt time and without), on diffferent platforms/devices, same result - Jitter.
As last time, WebGL on makes the jitters consistent and repeatable. WebGL off makes them random. Both WebGL and Fulscreen off makes the issue non-existant on the Cube demo, but on other more complex movements theres no effect.
