      With recent Intel integrated GPU drivers, and the lastest QtWebEngine with Viz composition, QtWebEngine applications will fail to launch with the following log:

      This issue can be worked around by editing src/core/api/qtwebenginecoreglobal.cpp and commiting out the line requesting ResetNotification.

      Since this is a feature that has to match between parent and child contexts, we are probably missing somewhere passing on the feature, or there is an issue with the Intel implementation.

        No reviews matched the request. Check your Options in the drop-down menu of this sections header.
