minimize maximize button popup reminder lightning Ubuntu
Hi everybody,
I use Thunderbird and Lightning for years, on Windows either Linux ; but here is the problem I have on Linux since Ubuntu 16.04 (and now 18.04 - 64 bits) : there is no minimize maximize button in the popup lightning reminder title bar ; only the close button. I searched for long times, how to add these missing buttons, but... nothing to do. These buttons are available on Windows system, but no more on Ubuntu. (I tried with a blank profile, without any else add-ons or themes, but it's the same).
Is there anyone can help me ?... Thank you for your help. Cristof.
