    • Fix clearing static tablet-target window in ~QWindow: 27316e097f95625aba19803ad8a47c4c0fece8fc, QWidgetWindow: 4dab27933db18bda3d2a3272bf1f07f68aa80985

    Description

      Application crashes, when closing windows with the second pen-key.

      To Reproduce:
      1. Configure button on pen to do Double Click
      2. Click on "Click Me..."
      3. Close appearing window with second button on a pen.
      4. Move over application window

      It neither crashes by mouse-press nor by press with the pen.

      Tested with wacom-tablet on windows x32 and x64 with recent stable-branch of qtbase.

      Simple test-application and backtrace attached...
