Hey,
I here my issue to know if I'm alone :)
Issue: After unlocking the phone, a graphical glitch sometimes appears—a black overlay that looks like a fragment of the multitasking/recent‑apps UI.
Expected behavior: Unlocking should display the home screen or the previously opened app normally, without any visual artifacts.
Actual behavior: Occasionally, a black area shows up immediately after unlocking, resembling a misrendered piece of the recent‑apps menu that sits on top of the normal UI. The rest of the screen remains visible underneath.
Frequency: Intermittent; it does not occur every unlock.
Reproduction steps:
Lock the device.
Unlock it (via fingerprint or PIN).
In some instances, the black overlay appears right away.
Additional notes: The problem appears to be purely graphical. A screenshot (not shown here) illustrates the glitch. The overlay disappears after further interaction, such as opening recent apps again or locking and unlocking once more.
