I have MS Office 2007 in wine 3.6 on Kubuntu 18.04. If I launch several Word documents, sometimes the mouse scroll stops working when switching to another document. Sometimes this issue can be solved by pressing Alt twice or by minimizing and maximizing the window, but it works until the next window switch. I've noticed that sometimes the mouse scroll affects the background window, as if Ctrl has been pressed, i.e. changes the font size. Is there a way to solve this problem?
It doesn't work at other my machine as well, so I think there is something with
Plasma rather than system configuration.
