Bug description:
  [Impact]

  The Nvidia driver corrupts and/or forgets its textures when resuming
  from suspend, by design. Documented here:

  https://www.khronos.org/registry/OpenGL/extensions/NV/NV_robustness_video_memory_purge.txt

  *NOTE* that this is actually not a common problem because the system
  must be using Nvidia as the primary GPU to be affected. So generally
  only desktop users will encounter the bug, not laptops. And even then,
  only desktops that use suspend/resume or VT switching may trigger it,
  if ever.

  [Workarounds]

  * Always log into a Xorg session and if corruption occurs then type:
  Alt+F2, R, Enter

  *

  [Test Plan]

  [Where problems could occur]

  [Original Bug Report]

  I recently installed ubuntu 20.04 on my computer, and I am running
  into an issue when I do the following:

  * Login with a user on desktop
  * Select switch user, and login as second user
  * Switch user again, and return to original user

  At this point, text and icons in the menubar / sidebar are corrupted.
  Text and icons in normal windows appear correctly. I have attached a
  screenshot of what this looks like.
