      Attached is a simple example containing ListView of delegates with GaussianBlur effect autoscrolling up & down.

      Running it with Qt 6.4 or dev shows memory usage in task manager growing. Also DropShadow causes this with Qt 6.4 but not with 6.3, as back then it didn't yet use GaussianBlur internally.
