Seems like NI has changed the indexing scheme in some version. For example, in LabVIEW 2011 32-bit Flat Right Triangle image is at 0xFF910460, but in LabVIEW 2022 32-bit it's at 0x43A. Moreover, those high contrast extra decorations, that@flarn2006discovered, are not sticky on the VI save - LabVIEW reverts them to the regular squares (just tested).
