[I'm not entirely sure about the STR or reproducibility here. This seems to repro after Fenix has gone into some sort of "suspended" state after I've let ~5+ minutes go by without opening it] ### Steps to reproduce 1. Open some web page in Firefox on Android. 2. Swipe up from the bottom of your screen to return to your home screen. 3. Allow 5-10min to pass (I'm not sure what the exact threshold is) 4. Tap the Firefox icon on your home screen to reopen it. ### Expected behavior Firefox reopens and shows me the page I was looking at. ### Actual behavior I get a weird flash of my homescreen as Firefox reopens. Specifically: - Android rapidly animates a Firefox app-window growing to fill my screen. (This window is partially-transparent when it's quite small, but it's fully opaque for most of the animation.) - Then, **when the Firefox window fills my screen**, it **briefly becomes transparent** so my home-screen shines through it, and then it becomes opaque again. ### Device information * Firefox version: 128.0a1 * Android device model: Pixel 8 * Android OS version: 14 ### Any additional information? (I have "Smooth Display" enabled, which activates high refresh-rate. I haven't tested without that setting yet, so I'm not sure if it's related to the bug or not; but it might help with making the bug noticeable, since the bad rendering is so brief.)
