    Description

      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.
