There are two big regressions about animations in current master compared to last stable release.
Those are blocking me for the animation tutorial videos, so it would be great to fix them as soon as possible.

Interesting note:
Actually on my laptop (with intel i5 dual core), those two bugs happen very rarely. Not never, but almost not enough to be not noticed.
However, on my desktop (with amd A10 quad core), they happen almost all the time.
(at least the pattern I found to trigger timeline-selection-reset/selected frame change when stopping playback is 100% reproducible there).
Dmitry, if you still have a computer with amd, may you check this issue on it?
