Run plasma from within gamescope

PlasmaNested.sh

#!/bin/sh

# Remove the performance overlay, it meddles with some tasks
unset LD_PRELOAD

## Shadow kwin_wayland_wrapper so that we can pass args to kwin wrapper 
## whilst being launched by plasma-session
mkdir $XDG_RUNTIME_DIR/nested_plasma -p
cat <<EOF > $XDG_RUNTIME_DIR/nested_plasma/kwin_wayland_wrapper

Any idea why notifications don't have a proper background when running in this mode. This is the case for action set change notifications.

I found a reddit post that solves my copy paste issue:

Might be of interest to any of you.

I've changed it up a little to add the dynamic resolution functionality from my previous comment:

#!/bin/sh

# Remove the performance overlay, it meddles with some tasks
unset LD_PRELOAD

# Get screen resolution
X=$(xdpyinfo -display :0 | awk '/dimensions/{print $2}' | cut -d 'x' -f1)
Y=$(xdpyinfo -display :0 | awk '/dimensions/{print $2}' | cut -d 'x' -f2)

rm -rf /tmp/desktop-mode
mkdir -p /tmp/desktop-mode
cat > /tmp/desktop-mode/kwin_wayland_wrapper << EOF
#!/bin/sh
$(which kwin_wayland_wrapper) --width $X --height $Y --no-lockscreen --x11-display $DISPLAY \$@
EOF
chmod +x /tmp/desktop-mode/kwin_wayland_wrapper

kwriteconfig5 --file startkderc --group General --key systemdBoot false
PATH=/tmp/desktop-mode:$PATH startplasma-wayland
kwriteconfig5 --file startkderc --group General --key systemdBoot --delete

This stopped working since plasma6 is there any workarounds ?
