The new version improved things a lot, but I believe there is still a
problem even if the severity of the bug could decrease.
Using the stylist when all paragraph styles are displayed takes really
long (scroll, right click on the styles)
The style properties windows is at is normal speed .
There is the same behavior with libreoffice-gtk2
If I remove libreoffice-gtk2 and libreoffice-gtk3 from my system, the
display speed is normal.
Using libreoffice 1:5.2.2~rc2-2 and libreoffice-gtk3 1:5.2.2~rc2-2 or
libreoffice-gtk2 1:5.2.2~rc2-2
