Kubuntu 22.04 kde Mouse lost focus and stuck When Close dialog too fast

I has been installed kubuntu 22.04, But there is a lot of errors:

1. Global menu allow for mouse moving window under it so I can't close moved window: [![weird window][1]][1] [1]: https://i.stack.imgur.com/6OnFP.png
2. Window cannot split 1/2 screen when moving to left/right edge like windows 10
3. Window cannot full maximum size when moving to top edge like windows 10.
4. When Close dialog too fast (like closing multi dialog confirm save dialog in visual code), Mouse will lost focus to anything and cannot click on anything (alt tab and keyboard typing still working) Util I run this command: kwin --replace
5. My EDRA keyboard error when press Fn + F1 will 'Mute behavior' But laptop Fn + F1 will behave
   Anyone who can fixed issues above or has been modding for fixed there issues?

Solution temp for fix

1. cause by multi-screen but difference resolution => cannot fix

4. I must create shortcut to reset kde Alt+Shift+Esc:

DISPLAY=:0 kwin --replace &

5. Remap key script

#!/usr/bin/env bash
echo for show keyboard code, run: xev
function BUL_askYesNo() {
    dialog --yesno "$1" 0 0;
    res=$?;
    echo result: $res;
    if [[ $res -eq 0 ]]; then
        clear
        echo you choose YES: remap keys
        xmodmap -e "keycode 232 = F1"
        xmodmap -e "keycode 233 = F2"
        xmodmap -e "keycode 128 = F3"
        xmodmap -e "keycode 212 = F4"
        xmodmap -e "keycode 237 = F5"
        xmodmap -e "keycode 238 = F6"
        xmodmap -e "keycode 173 = F7"
        xmodmap -e "keycode 172 = F8"
        xmodmap -e "keycode 171 = F9"
        xmodmap -e "keycode 121 = F10"
        xmodmap -e "keycode 122 = F11"
        xmodmap -e "keycode 123 = F12"
    else
        clear
        echo you choose NO: reset to default
        setxkbmap -option
    fi
}
BUL_askYesNo "For show keyboard code, run: xev \n----\nRemap keyboard choose YES, reset choose NO "
