Yosemite breaks rounded rect corners in UI overlays, like the ones triggered by volume and brightness changes. The masking is broken when the translucent blur shaders aren't applied.
You'd think that'd something they would easily catch in QA before 10.10 shipped, but it's still broken even in 10.10.1.
