      Description

      When I'm using the official Archlinux package for QtWebEngine, everything works fine.

      However, when I'm using a custom built package (which disables stripping, adds -ggdb3 -fvar-tracking-assignments -Og to CXXFLAGS and builds with a qtbase with -release -force-debug-info), I only get a blank page and this as soon as I open a page:

      This currently keeps me from testing the patch for QTBUG-54769 and I have no idea what's happening...
