Hook: Hook `com.android.server.wm.RecentTasks.isVisibleRecentTask(com.android.server.wm.Task)` for apps set to `Hide task`.

35+
For apps set to `Hide preview`, hook `com.android.server.wm.TaskSnapshotController.getSnapshotMode(com.android.server.wm.Task)` and `com.android.server.wm.ActivityRecord.shouldUseAppThemeSnapshot()` so selected apps use an app-theme task snapshot instead of a real screenshot. `com.android.server.wm.Task.getSnapshot(boolean, boolean)` is also hooked to avoid returning previously cached real snapshots.
