Created attachment 354693 [details] Test case After the changes to compositing in bug 90342, a style change that affects a composited layer's transform and simultaneously changes another property triggering repaint will no longer trigger a compositing geometry update, so the GraphicsLayer's transform never gets updated. For example, after changing both the background-color and the transform of a composited layer, the layer gets repainted with the new color but doesn't move.
