Hey guys, so sorry you're hitting this problem!
Can someone who is hitting this problem try checking/unchecking the VMware Fusion > Preferences > Keyboard & Mouse > Mac Host Shortcuts > Enable Mac OS Host Keyboard Shortcuts checkbox and see if that makes this any better or worse? This checkbox is checked by default, so my assumption is that most people on this thread will have this box checked already. Unchecking this may help alleviate this problem temporarily until we can get the problem fixed.
If people could try this and see if it helps, I'd appreciate it. So I guess my questions for those hitting this problem are:
1) Do you have the VMware Fusion > Preferences > Keyboard & Mouse > Mac Host Shortcuts > Enable Mac OS Host Keyboard Shortcuts checkbox checked when you are hitting this problem?
2) If so, does unchecking this checkbox help?
3) If not, does checking this checkbox help?
Hm, also, what Fusion view mode are people using when they see this? Single Window, Fullscreen, or Unity?
And, just to clarify... is this happening in combination with Cmd+Tabbing in and out of the VM, or ungrabbing or switching between applications in the macOS host at all? Or should I be able to reproduce this by just opening a Win10 VM in single window mode, say, open Notepad, and type, occasionally holding shift and control occasionally and pressing other normal keys, without losing focus from the Win10 VM?
Thanks!
