Xubuntu 中的超级 L 键双触发晶须菜单

Question

在升级到 Xubuntu 22.04 之前，我会点击左侧的 Windows 键 (Super L)，它将打开 xfce 中的 Whisker 菜单。升级后，每当我按下同一个键时，就好像我快速连续输入两次一样。我相信这是因为我有一些映射该键的东西。当我运行时，xev -event keyboard我得到两个 Windows 键的以下信息：

右 Windows 键

KeyPress event, serial 28, synthetic NO, window 0x6a00001,
    root 0x1df, subw 0x0, time 484880404, (423,18), root:(1294,553),
    state 0x10, keycode 134 (keysym 0xffec, Super_R), same_screen YES,
    XLookupString gives 0 bytes: 
    XmbLookupString gives 0 bytes: 
    XFilterEvent returns: False

KeyRelease event, serial 28, synthetic NO, window 0x6a00001,
    root 0x1df, subw 0x0, time 484880476, (423,18), root:(1294,553),
    state 0x50, keycode 134 (keysym 0xffec, Super_R), same_screen YES,
    XLookupString gives 0 bytes: 
    XFilterEvent returns: False

左 Windows 键

FilterEvent returns: False

当我运行时xmodmap，我得到以下输出：

xmodmap:  up to 4 keys per modifier, (keycodes in parentheses):

shift       Shift_L (0x32),  Shift_R (0x3e)
lock        Caps_Lock (0x42)
control     Control_L (0x25),  Control_R (0x69)
mod1        Alt_L (0x40),  Alt_R (0x6c),  Meta_L (0xcd)
mod2        Num_Lock (0x4d)
mod3      
mod4        Super_L (0x85),  Super_R (0x86),  Super_L (0xce),  Hyper_L (0xcf)
mod5        ISO_Level3_Shift (0x5c),  Mode_switch (0xcb)

然而，我确实不是有一个~/.Xmodmap文件。我确实有一个~/.Xauthority文件，但它看起来是二进制/不透明的。

我认为需要通过xmodmap（或可能setxkbmap）取消设置某些内容，但我不知道那会是什么。
