I'm French and use the French keyboard layout on my Mac. I occasionally use the American keyboard, so I've it in the keyboard layout menu (not sure of the english name, it's the one on the right next to the date with the little flags)
Sometimes, when I am in "coherence" and I click on a window from a Windows 10 program, to switch to Windows, the keyboard layout automatically switches to American.
First , I thought that I was using a wrong shortcut inadvertently (I do not alway notice straight away the change of keyboard, especially as most keys are in the same place), but the keyboard shortcut for changing language was off. Then I saw it from the corner of my eye : when I clicked on a window , the little flag changed from the French to the Amercan one. This is very inconvenient. I use Parallels to be able to switch from Mac to Windows, and I have to look at the little flag to know if I've switched to American each time I go back to Windows.
It seems that happens since I use Windows 10, though I'm not 100% sure. Windows is installed in French as is Mac OS . (high sierra)
