You'd think that they'd prominently annotate everything with "introduced in vX.Y". Anyway, with the feature no longer defaulting to on we have some time to root cause this, and if indeed it is the panel in the ThinkPad (I think it's an LG display; can provide more information if necessary) rather than a matter of incorrect logic, then the solution would be a panel quirk.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are on the CC list for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
