…indowServer GPU load (#48376) fix: macOS stop overriding private cornerMask API to fix WindowServer GPU load spike Electron fetched a custom `_cornerMask` for `ElectronNSWindow` to smooth vibrancy corners. On macOS 15 (Tahoe) that private hook forces the window shadow to be rendered from a fully transparent surface, causing the WindowServer GPU load regression. Remove the `cornerMask` property and the `_cornerMask` override so we stay on Apple’s default shadow path. Co-authored-by: avarayr <7735415+avarayr@users.noreply.github.com>
