    Description

      QtWebEngineProcessd.exe is excessively using CPU and finally crashing.

      After running some indefinite time with high cpu usage, the exe is crushing.

      Callstack and CPU usage images can be found on attachment.

      Same situation is not seen in release version of this exe and in older version (5.7.1).  This exe is started by QWebEngineView from my main process.

      Thanks.
