Research direction

Reproduce the issue from Appearance settings with a background image, then enable experimental.useBackgroundImageForWindow in settings.json and compare the active-pane tab with the Settings tab. Trace the desktop tab rendering path responsible for active-pane transparency; done means the active tab has the expected opacity while the experimental feature is enabled.
