I executed 'journalctl -b -f' to get the logs (they are in the file) and executed systemctl suspend.

Documented here: https://www.khronos.org/registry/OpenGL/extensions/NV/NV_robustness_video_memory_purge.txt Although it's so awkward to implement everywhere that realistically compositors will never support it fully. Instead we're waiting for an Nvidia driver fix. *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 and VT switching may trigger it, if ever. Even in development the bug cannot be reproduced reliably. [Workarounds] * Always log into a Xorg session and if corruption occurs then type: Alt+F2, R, Enter * https://download.nvidia.com/XFree86/Linux-x86_64/510.54/README/powermanagement.html#PreserveAllVide719f0 [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.
