      The new macOS 26 results in various rendering issues in our macOS style, both in Widgets and Quick. This is a tracking bug for these issues.

      Note: The new Liquid Glass UI is only enabled on macOS for apps built against the macOS 26 SDK, effectively opting in to the new UI. The app's linked SDK is the distinguishing factor, not the linked SDK of the Qt libraries. This means we need to check QMacVersion::buildSDK(QMacVersion::ApplicationBinary) in addition to a runtime check for the current OS version. It's also possible to opt out of the new UI via a UIDesignRequiresCompatibility key in the Info.plist, so we need to check that too.
