AMD GPU display went blank after enabling full composition pipeline in nvidia xserver settings

Just installed Manjaro KDE, latest stable build. Was experiencing a lot of screen tearing on my Nvidia connected display (especially on youtube, etc.). Found that ‘enable force full composition pipeline’ is a solution. Saved to /etc/X11/mhwd.d/nvidia.conf and the screen tearing was solved. At this point, the AMD powered display was working without a problem. After a reboot though, The AMD powered monitor just shows a blank screen.

System config:
AMD Ryzen 9 3900x
16GB 3200MHz
GPU1: Colorful RTX3060
GPU2: Sapphire Pulse RX5600XTBE
Monitor 1: LG 1920x1080 75Hz via HDMI
Monitor 2: LG 1366x768 via VGA-HDMI converter

What bothers me is that disabling ‘force composition pipeline’ and rebooting doesn’t bring back monitor 2 and the tearing doesn’t come back either. Any hints at what I am doing wrong??
