VTK 8.2.0 + Qt 5.12.2 weird event queue processing

I just checked and found that

  • under the vmware player even with 3d graphics acceleration enabled
  • with the latest Centos 7.6.1810
  • with Qt 5.9.2 from centos repo
  • with VTK 8.2.0 built from source
    problem can be reproduced each time on the mentioned above example
