Description

Version

v2.7.1

Environment

Windows 11 25H2

Steps to reproduce

  • Launch LightBulb and ensure it is actively controlling brightness.
  • Set brightness to a lower level (e.g., 30–50%).
  • Open Windows Quick Settings panel (Win + A).
  • Observe the brightness slider behavior and screen brightness.
  • Close the panel and re-check brightness level.

Details

  • Expected behavior: Brightness should remain at the value set by LightBulb. Opening Quick Settings should not override or reset the brightness value.
  • Actual behavior: - On the first time opening Quick Settings after setting a low brightness: Screen brightness briefly returns to default/normal level. - After closing and reopening or adjusting again: Behavior stabilizes and brightness stays correct.
