The Firefox Picture-in-Picture window fails to maintain its "Always on Top" focus or visibility during workspace and task switching, persisting despite a clean OS reinstall, stable NVIDIA driver setup, and extensive browser configuration tweaks.
System Configuration
- OS: Pop!_OS 22.04 LTS (Clean install).
- GPU: NVIDIA GeForce RTX 4050.
- Driver: system76-driver-nvidia (Enabled).
- Graphics Mode: Hybrid (Command: system76-power graphics hybrid).

Firefox Picture-in-Picture (PiP) Issue
- Problem: PiP window loses "Always on Top" focus or vanishes when switching workspaces/tasks.
- Config Changes: Set 'focusmanager.testmode' to true and 'media.videocontrols.picture-in-picture.video-flips-visibility-on-focus-change' to false.
- Window Settings: Focus set to "Click" via GNOME Tweaks/Settings.
- Environment Test: Tested launching via 'MOZ_ENABLE_WAYLAND=0' to bypass Wayland focus logic.
Software & Tools
- Tweaks: Installed for font hinting (Slight) and window behavior management.
