1) Description:	Ubuntu Cosmic Cuttlefish (development branch)
Release:	18.10

2)xwayland:
  Instalado: 2:1.20.1-3ubuntu2
  Candidato: 2:1.20.1-3ubuntu2
  Tabela de versão:
 *** 2:1.20.1-3ubuntu2 500
        500 http://br.archive.ubuntu.com/ubuntu cosmic/main amd64 Packages
        100 /var/lib/dpkg/status

3)While the video plays, it shouldn't drop a single frame, but Ubuntu
with Wayland (selected on login screen) is dropping way too many.

4)When watching videos on Google Chrome, or Mozilla Firefox, or any
other web browser (using Wayland on login screen), with the hardware
acceleration option on, the video drops around 15 to 20 frames for every
100 frames at 60FPS videos (half of that on 30FPS). I know that my iGPU
(Intel HD Graphics 2000 is old, but on Win8.1 or Win10 it didn't drop
any frames, 60FPS without drops).
