Maybe this is a Breeze bug?
Comment 3 Nate Graham 2025-12-10 17:00:53 UTC 
I'm not noticing the "noticeably white" observation in your screen recording. Can you point it out?

Comment 6 Fernando M. Muniz 2025-12-10 17:21:10 UTC 
As you can see by comparing, the screen locker adds a layer of white over it.
Comment 8 Fernando M. Muniz 2025-12-11 06:36:29 UTC 
How do I disable it? This makes me think my screen is dirty.
Comment 9 David Edmundson 2025-12-11 11:47:03 UTC 
The blur is intentional for readability.
