Some trouble I experience with Ubuntu 14.04 and Gnome-session-flashback

• nemo crashed
• xprop -set _net_wm_strut_partial gets overwritten frequently
• login screen changed after running out of battery in suspended state
• libreoffice (4.2.7) calc and writer failure: when setting font color, gnome-panel turns invisible, (but still works, when I click to the places where the buttons should be, they function well) and right-click menus inside libreoffice disappear.
  (can be restored with sudo pkill gnome-panel, but is frequent (more times a day) and annoying.)
• libreoffice (4.2.7) is extremely slow: it's lagging!
• libreoffice (4.2.7) calc formatting is incorrectly shown. Cells with the same formatting appear differently: fonts mismatch in size and style (serif/sans-serif)
• libreoffice (4.2.7) calc graphical interface elements are incorrectly shown. checkboxes sometimes have checkmarks, sometimes don't.

I upgraded to LibreOffice 4.3.3 using this method.
