+ - [QTBUG-84226] Added support for environment variable
+   QT_WAYLAND_FORCE_NONBLOCKING_SWAP_SUPPORT, which can be used to force the
+   resolution of detecting if EGL driver supports non-blocking eglSwapBuffers
+   call. If you encounter application freezing while waiting indefinitely for a
+   buffer swap, then try setting variable to 0.
