+Subject: [PATCH] test-display-base.cpp: adjust designated init for C++20
+
+Adjust designated initializer to be C++20 compliant. Starting with
+g++-16, GCC will default to the C++20 standard.
+
+Note: v3 was acked by the maintainer on the spice-devel mailing list
+in December 2025 but was never merged.
