Jeez, I wasn't ware that this is in such a bad shape for Qt.
I see most problems are related to discrete animations.
Say rect.x gets animated from x=10 to x=100 exactly at 2s (discrete calcMode).
Then I sample at 1.999s and 2.001s (once before it changes, once afterwards).

Is it possible that SharedTimerQt works differently then the Mac/Chromium/.. timers leading to precision problems? I'm not sure at all. :(

Ossy said these problems aren't reproducable. I can't debug this w/o a Qt environment - can anyone take this over?
