    Description

      When running the "customrendernode" example: https://code.qt.io/cgit/qt/qtdeclarative.git/tree/examples/quick/scenegraph/customrendernode?h=6.5

       

      We are seeing a large amount of threads being spawned (87 in the example above)

      We are also seeing similar behaviour in our code base, with 100-200 extra threads being spawned.

       

      They seem to be NVIDIA related (nvwgf2umx.dll)

      (Tested on Windows 11)

       

      Is this expected behaviour or a bug, it seems quite excessive.
