The main problem was that inside the effect there was manualVerticalAngle, which did not represent the actual rotation angle of the cube during the animation, but used to calculate the position of the reflection. The actual angle was calculated on-the-fly and was not exposed outside. Brief description of what the code does: - variables currentAngle and verticalCurrentAngle now always represent the current position of the cube. They are updated when one uses the mouse and inside the rotateCube() method, which is called in prePaintScreen(). - two queues, animations (used for Start / Stop / Left / Right) and verticalAnimations (used for Up / Down) are used for scheduling the animations if i.e. user presses several keys in a row. The code checks whether the last animation has finished (and thus we need to start a new one) inside prePaintScreen() and postPaintScreen() - when the animation starts, code saves the starting position of the cube inside startAngle, startFrontDesktop and verticalStartAngle variables, which are used to calculate the actual cube position during the animation later. This is done by startAnimation() and startVerticalAnimation(), which also calculates the QTimeLine curves needed for animation BUG: 213599 BUG: 373101 Differential Revision: https://phabricator.kde.org/D9860
