Forgot to add:

When I press and depress the left Microsoft Windows logo key with xev
having focus, the events are:

KeyPress event, serial 37, synthetic NO, window 0x5c00001,
    root 0x3cb, subw 0x0, time 60567700, (116,80), root:(1826,1536),
    state 0x10, keycode 133 (keysym 0xffe7, Meta_L), same_screen YES,
    XLookupString gives 0 bytes:
    XmbLookupString gives 0 bytes:
    XFilterEvent returns: False

KeyRelease event, serial 37, synthetic NO, window 0x5c00001,
    root 0x3cb, subw 0x0, time 60567892, (116,80), root:(1826,1536),
    state 0x50, keycode 133 (keysym 0xffe7, Meta_L), same_screen YES,
    XLookupString gives 0 bytes:
    XFilterEvent returns: False

When I press left Microsoft Windows logo key + d with xev having
focus, the events are:

KeyPress event, serial 37, synthetic NO, window 0x5c00001,
    root 0x3cb, subw 0x0, time 60643492, (89,77), root:(1786,1513),

    XLookupString gives 0 bytes:

showing that state bit 0x40 gets set on the "d" press.

"xmodmodmap" output:

shift       Shift_L (0x32),  Shift_R (0x3e)
lock        Caps_Lock (0x42)
control     Control_L (0x25),  Control_R (0x69)
mod1        Alt_L (0x40),  Alt_L (0xcc)
mod2        Num_Lock (0x4d)
mod3        ISO_Level5_Shift (0xcb)
mod4        Meta_L (0x85),  Super_R (0x86),  Meta_L (0xcd),  Super_L (0xce),  Hyper_L (0xcf)
mod5        ISO_Level3_Shift (0x5c)

I tried "xmodmap -e 'remove mod4 = Super_R Super_L Hyper_L'" to get

mod4        Meta_L (0x85),  Meta_L (0xcd)

+ start a new emacs, but it did not change anything.
