I use Fedora with Cinnamon desktop environment. I use the workspaces feature heavily in that, my browser is on a dedicated namespace, IDE and terminal are on a dedicated namespace, and mail client on another.
When you switch between namespaces, Cinnamon shows the workspace name in the center of the screen as a notification which goes away in probably less than a second. This wasn’t a problem till now. While switching between browser and IDE workspaces too often, this workspace name notification came in way and I had to wait before continuing doing anything on the workspace I switched to.
To disable this notification:
System Settingsfrom the Cinnamon start menu
- Toggle the option
Enable workspace OSD
