I've been having this problem quite a long time. I really want to fix it.
when I zoom in or out without any windows opened suddenly the vertical scroll bar disappear.
but if I open window f2,f3 it appears but if I close these windows it disappears again.
it's random! sometimes it shows but sometimes it doesen't
it is really annoying...
please help me. I am using windows 10, 1920*1080
<with mixer window opened>
<no windows opened>
