Bug description:
  Hi,

  After upgrade from Ubuntu Mate 19.10 to Ubuntu Mate 20.04 i cannot use
  a resolution of 1366x768. Screenshot attached. I am using an Asus
  vivoBook laptop with Amd Ryzen 3 and a Radeon Vega Graphics AMD.

  I found someone in reddit reporting the same problem:
  https://www.reddit.com/r/UbuntuMATE/comments/ggq8g5/problem_with_resolution_1366x768_with_ubuntu_mate/

  All other screen resolutions OK.

  
  Many thanks
