    Description

      In Qt 6.8.2, any timer created in a plugin by calling the startTimer() function, when the program terminates, displays the console message: "QObject::~QObject: Timers cannot be stopped from another thread". In Qt 6.8.1, there is no such message.

      The test application (attached) and Qt Designer (by copying libtestplugin.so to QTDIR/plugins/designer) give the same results.
