      Starting from 6.5.1, Direct3D was automatically enabled on QtWebEngine, and it will let the software added 50 additional threads.

      You can build the sample "simple browser" with 6.4.3 and 6.5.1 on windows, and check the application threads count. 

      The 50 additional threads seem to be CPU testing threads when collect the cpu features? But after test not terminate.
