Bug ID: 47403
           Summary: ALT+TAB results in a sticky ALT in the application
                    when switching back
           Product: Wine
           Version: 4.10
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown

I noticed the following issue when playing EVE Online: If you use the ALT+TAB
key to switch from EVE Online to another application and then return back to
EVE Online, then the EVE Online is still thinking you are still holding down
the ALT key. This is only resolved by pressing and releasing the ALT key again.
It's really annoying.

Hypothesis: When pressing ALT+TAB (which at least for me usually happens in the
order 1. hold ALT down and then 2. press TAB) the ALT-key-down command is
transferred to the application (EVE Online) and then the focus is changed to
another application, without sending prior the ALT-key-down command. In my
opinion this should be changed. If ALT+TAB is used to switch the application,
the ALT-key-down command should be generated prior switching.
