    Description

      QTBUG-82914 fixed leaking callback timers in 5.12.9:

      https://codereview.qt-project.org/c/qt/qtwayland/+/294949

      https://codereview.qt-project.org/c/qt/qtwayland/+/296293

       

      Those changes were also cherry-picked into 5.15:

      https://codereview.qt-project.org/c/qt/qtwayland/+/298454

      https://codereview.qt-project.org/c/qt/qtwayland/+/298455

       

      This was never fixed for 5.13 or 5.14. Specifically, Qt applications on Fedora (using 5.14.2) and Gnome are usually spinning at least one 100ms timer even while inactive, easily visible with strace.
