Is Wayland matured on Ubuntu

On Ubuntu 22.04, for the sake of Waydroid, I gave Wayland a try. Without knowledge of the root causes of the following issues, I'd just hold on for a while before switching. 

  1. Chrome/VS Code fonts are blurry, once display scaling is enabled. 
  2. Chrome and Prospect Mail blink often during rendering. 
  3. Laggy mouse/windows dragging sometimes.
Is it caused by Nvidia GPU compatibility?

Ubuntu and Bluetooth Call

Here is a note for Ubuntu install. Bluetooth A2DP and HDP modes were always messed up by default, i.e., I can't really use Bluetooth microphone to make teams/zoom call. Seems replacing PulseAudio with Pipewire/wireplumber solve the problem smoothly. Refer to here.

Slow Ubuntu Bootup Troubleshooting

To analyze the reasons slowing down Ubuntu bootup, please use systemd-analyze cmd. 

systemd-analyze time
Startup finished in 5.027s (kernel) + 11.220s (userspace) = 16.247s
graphical.target reached after 11.194s in userspace
To sort modules by time taken during boot, use
systemd-analyze blame
We can see snap modules took quite long to load. But snap are loading in parallel and doesn't block others. We can see critical path:
systemd-analyze critical-chain
graphical.target @11.194s
For me, removing a USB card reader helps, due to BIOS/UEFI?
