This bug also occurs when staying in one of the voice channels on Discord for prolonged periods of time.
There is something interesting I've noticed about this bug though, it only occurs on X11 Display Server, it never occurred when I used the Wayland Display Server. So maybe this bug could also be a bug in the X11 Display Server? I would also recommend testing this bug in different Desktop Environments as well, just to be sure if this is just gnome-shell 3.x and it's forks, or if it's actually the X11 Display Server itself. Also, logging out of the session can fix the issue temporarily (until the steps are followed to reproduce the bug again). I have also reported the bug in [here](https://github.com/linuxmint/cinnamon/issues/3442#issuecomment-997984435) and [here](https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/4889) OS Information: Linux Kernel version: 5.4.0-91-generic Distribution release: Ubuntu 20.04 Distribution version: 20.04.3 LTS DE Information: GNOME version: 3 GNOME Shell version: 3.36.9 Display Server Information: Display Server: X11 Display Server Version: X.Org 1.20.11 Display Manager Information: Display Manager: gdm3 Processor Information: Hardware: Intel(R) Core(TM) i3-6100 CPU @3.70GHz Cores: 2 Threads: 4 Video Card Information: Hardware: NVIDIA Corporation: GM206 [GeForce GTX 950] Driver: nvidia-driver-470 (proprietary, tested) Here's one of the best ways to reproduce this issue: 1. Open Discord 2. Enter into any voice channel on Discord and just stay there for a day, it may range from 30 minutes to 24 hours for it to occur. Expected results: The text shouldn't vanish from the desktop environment and it shouldn't cause any graphical issues. Instead, if anything stops working, it should reload! And the Settings app should open without crashing. Actual results: The text vanishes from the desktop environment and/or other graphical errors occur, and the GNOME settings app crashes upon attempting to open.

I don't see the hours, but i see the icons like Firefox actually opened, my battery etc. and notifications are empty (just the "!" icon). Text normally displayed when mouse-hover the applications icons is not displayed, when Ubuntu ask for my password the frame display only 3 or 4 characters, when i put the computer in standby and reopen it doesn't change anything, and the bullets of my password aren't displayed when i login. The text normally displayed on the menus aren't displayed too, same for the application menu (when hitting the bottom left corner button) and icons of applications (like Discord options on the top right of the screen). The only text from xorg that is displayed (if it's from xorg…) is the window's title (like "#Room - Discord" for Discord application, or "me@computer: ~/" above the terminal). What is left works : Firefox can display text, and text is displayed in settings for example. P.S: a reboot solved the problem.
