Selector moves on its own in 16:9 ratio with Bluetooth controller connected

After loading, the onscreen cursor to select game mode switches down continuously while a Bluetooth controller is connected and the aspect ratio is set to 16:9 on the Samsung Galaxy Z-Fold 5. Issue was repeated on multiple controllers and is resolved by switching back to full screen aspect ratio. Android app was just updated today to 1.20.15.01 and cannot be selected in this bug report.
