discrete GPU

Product: plasma-login-manager

Hello,
I am using Arch Linux and as the title says after installing the new
plasma-login-manager and enabling it and also disabling sddm when I try to
launch a game I get a complete black screen in the game window but I can hear
the game sounds. If I alt+tab I can see the other windows just fine but the
game window is completely black.
When I do nvidia-smi in the console I can see the game exe running. If I do
systemctl status plasmalogin this is what I get:
archlinux plasmalogin-helper[1027]: [PAM] returning.
archlinux plasmalogin[802]: Authentication for user "****" successful
archlinux plasmalogin-helper[1027]: pam_kwallet5(plasmalogin:setcred):

archlinux plasmalogin-helper[1027]: pam_unix(plasmalogin:session): session

archlinux plasmalogin-helper[1027]: pam_kwallet5(plasmalogin:session):

archlinux plasmalogin-helper[1027]: Starting Wayland user session:

archlinux plasmalogin[802]: Session started true

archlinux plasmalogin[802]: Auth: plasmalogin-helper exited with 255
archlinux plasmalogin[802]: Greeter stopped.
PLASMALOGIN::Auth::HelperExitStatus(255)
STEPS TO REPRODUCE
1. Install and enable the new plasma-login-manager
2. Launch a game using the nvidia discrete GPU
OBSERVED RESULT
The game window is completely black but I can hear sounds.
EXPECTED RESULT
The game window should display correctly
