open tabs are disappeared

  • Sometimes will open a new window of Vivaldi - haven't figured out the pattern. Sometimes I copy something with CTRL+C and suddenly additional Vivaldi window will open. Regardless of that it is already opened. I close that newly opened window and then I discover that also that another window is closed with lots of tabs I really need. I have the setting that open last session. As I closed empty window then also all my opened tabs are gone. Very frustrating. It has happened several times and I cannot understand why it happens. Also I do not know, whether it is Linux-specific issue or not as I am using Linux Mint 18.3 currently, 64-bit with MATE desktop. I checked my shortcut keys - these are like in MATE desktop environment are by default.

    My environment
    Vivaldi 1.13.1008.40 (Stable channel) (64-bit)
