Probably would not hurt for you to provide the name of DM and DE being used.

Offhand I would guess you are running some gnome app in a Plasma DE.
Check ~/.xsession-errors. Verify all user files owned by user;
find $HOME \( -not -user $USER -or -not -group $USER \) -exec ls -ald '{}' \;

Suggest creating/running in a test account to see if having same problems.
If not, then start modifying the test account to run the same as the
failing account.

Looking like a xfce user running under a Plasma DM type install.

Noticed you did not indicate if a clean/new user test account has same
problem or not. mga7 had two or more xfce releases where you should have
seen the message to reset xfce desktop.

cat /usr/share/doc/mageia-xfce-config/README.update.urpmi

I run xfce under lightdm and have unchecked
Launch GNOME services on startup
xfce4-settings-manager->Session and Startup->Advanced->Compatibility

Again, I suggest a clean test account verification before any further
research.
