WASM: DropShadow leads to misrendering in other places

    XMLWordPrintable

    Details

    • Platform/s:
      WebAssembly

      Description

      This is a follow up of QTBUG-71099. I've created a minimum playground which shows side effects when using DragShadow in a WebAssembly application.

      Problem:

      The ListView contains styled items with borders. These borders are not visible in the WebAssembly target. Removing the DragShadow from the FooterButton makes them visible.

      Code is here:
