Too little contrast between focused and backdrop windows

[stradicat]

What Happened

There's too little window titlebar contrast between active and inactive windows.

This is especially visible while using the Light theme, but the Dark theme also has a tad too low of a contrast.

Examples:

Firefox: Active window:

Firefox: Inactive window:

Files: 2 windows side by side

Expected Behavior

Enough visible contrast to evaluate which window is currently active, if multitasking between windows of the same application. Inactive window font colour could be dimmed, too.

Steps to Reproduce

1. Open an application, e.g. Files (native) or Firefox (GTK-based)
2. Open a new window from that app
3. Put windows side by side
4. Quickly decide which window is currently active

Your Firefox screenshot here appears to be using Adwaita, and regardless, we can't control how Firefox renders (as it's not rendered using GTK, but uses custom drawing that tries and often fails to emulate GTK). However, the Files screenshots do demonstrate a lack of differentiation between states, and is more obvious there than in other apps. 👍

Understood, chief; thanks for the explanation!
