[Bug 1446865] Re: KDE5/Qt5 does not support session restoration

 

Here is a very helpful comment from Thomas Lübking from kde-bugs
#341930:

KWin is not responsible for restarting applications.
This bug was *only* about not restoring window manager attributes (position,
virtual desktop, etc.) on session restorage.

There're fundamental bugs in Qt5 that prevent (both, correct and entire)
restoring of Qt5 applications, see

** Description changed:

- I use the setting "On Login : Restore previous session".  I also use
- several virtual desktops.
- 
- When I open a KDE5 session, all windows are opened on the first virtual desktop.
- With KDE4 all windows were restored on their virtual desktop, which is the expect behaviour.
+ KDE5/Qt5 does not support proper session restoration.
