Description
Steps to reproduce:
1) Clone the most recent examples from the Qt3D 5.15 branch.
2) Build the Scene3DView example against 5.15.2 (I used my distro's binaries).
3) Run the example and resize the window.
Outcome:
QSGRendererThread segfaults with the following (partial) stack trace:

Edit: Updated the stack trace (with a build from git).
