Materialize the shimmer sweep behind a Loader gated on visibility so no animation object exists (and the render thread can park) when the placeholder is hidden, and replace the Qt5Compat LinearGradient (an extra ShaderEffectSource pass) with a native Rectangle gradient. The rounded OpacityMask pass is kept for exact visual parity (incl. circular avatars).
