Fedora 32, Gnome Wayland, Qt 5.14.2
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.
