Docking or undocking a laptop, or flipping display modes with Win+P, can leave the Dock empty, missing, or misconfigured. Fixes #48516. The root of it: the Dock's per-monitor config leans on a stable hardware ID for each monitor. Right after a `WM_DISPLAYCHANGE`, before Windows has settled the new topology, that lookup can come back empty or fall back to a volatile GDI name. The reconciler then reads that as "hey, a new monitor showed up" and creates a fresh, disabled, empty config for a monitor that never actually left. On top of that, a burst of `WM_DISPLAYCHANGE` messages during a mode switch each triggered an immediate write to settings, so one bad intermediate snapshot could get baked in permanently. And since only the Dock window itself was listening for `WM_DISPLAYCHANGE`, the Settings page's monitor list could go stale whenever no Dock window happened to be alive. ## The plan - Retry the stable-ID lookup a few times before giving up and falling back to the volatile name. - Debounce monitor-change handling so a flurry of `WM_DISPLAYCHANGE` events settles down before we reconcile and persist, instead of writing every half-finished intermediate state. - Have the main window forward `WM_DISPLAYCHANGE` too, so the monitor cache stays fresh even when the Dock is off or has no windows up. - Teach the reconciler to reassociate a secondary monitor's config with its new ID when there's exactly one unmatched monitor and one unmatched config, the Win+P round trip case, instead of treating it as new hardware. - Added tests covering the transient ID fallback, the ambiguous multi-monitor case, and the Win+P reassociation. Scaling behavior when the Dock lands on a monitor with a different DPI is a separate issue (#48466) and isn't touched here. --------- Copilot-Session: d2bc281b-062c-4e6e-9356-bdb7a2ef9e1e
