This remains until the device is rebooted. And it seems that the reason behind this is that the nvidia gpu gets enabled after waking the system up.

@DuttaAB-dev , what are your current power settings so I can try to replicate the issue.

Battery saver from the power menu. And also if it isn't obvious, the test has been performed in integrated graphics mode.
