Screen rotation turns the display on Raspberry Pi 5 and generic arm64 boards
The Screen rotation setting did nothing on a Raspberry Pi 5. From Anthias 2026.07.0 it turns the whole display there, and on generic arm64 boards such as the Rock Pi 4, as soon as you save.
On a Raspberry Pi 5, picking a value in Settings > "Screen rotation" saved without complaint and left the picture as it was, as the 2026.05.1 entry that introduced the setting described. From Anthias 2026.07.0, "Portrait (90°)", "Landscape, inverted (180°)" and "Portrait, inverted (270°)" turn the whole display on a Raspberry Pi 5, and the change applies as soon as you save, with no reboot. In this release 90° and 270° turn the picture the opposite way to a 32-bit Raspberry Pi 2 or 3; Anthias 2026.07.3 makes every board turn the same way.
The same fix covers generic arm64 boards such as the Rock Pi 4, which run the viewer the same way as the Pi 5.
