Meeting's report not saving in full screen

Hello, 

I had many times a problem with meeting's report. 
During meetings, I take notes in the "meeting's report" section, in full screen (I also make modifications in actions / tickets in another screen at the same time),
and many times, when I reduce the window at the end of the meeting (even after a "ctrl + s"), the report was not saved and I loose all or part of my report. 

I cannot reproduce the problem during my test session but have you any idea of what happens ? Is there something wrong with working on actions / tickets while writing the report ? 

Thanks for your help,

Best regards
