A software bug in Wear OS 6 and 6.1 is causing display overlap issues on third-party watch faces for Google Pixel Watch and Samsung Galaxy Watch models. The problem, which appears after prolonged use of a watch face, causes faded elements of the always-on display to remain visible and overlap with the active watch face, impacting readability. Both Google and Samsung are reportedly aware of the issue, which has been documented on Google's IssueTracker since October.
