Description of problem: Just rebooted & was restoring my many virtual desktops, after upgrading the kernel to 4.6.5-200.fc23.x86_64 via dnf. May be something to do with moving the window for Epiphany, or one of the other 3 browsers I initiated at more or less the same time: Firefox, PaleMoon, & Seamonkey?

*********** MASS BUG UPDATE ************** We apologize for the inconvenience. There is a large number of bugs to go through and several of them have gone stale. Due to this, we are doing a mass bug update across all of the Fedora 23 kernel bugs. Fedora 23 has now been rebased to 4.7.4-100.fc23. Please test this kernel update (or newer) and let us know if you issue has been resolved or if it is still present with the newer kernel. If you have moved on to Fedora 24 or 25, and are still experiencing this issue, please change the version to Fedora 24 or 25. If you experience different issues, please open a new bug report for those.
Now on F24 & using kernel 4.7.4-200.fc24.x86_64, not seen the problem again.
thank you for letting us know
