SUMMARY The only ways to read the file name from the desktop, is by using the "Properties" option in the context menu or by using the rename option. When hovering over the file, no popup is displayed. Clicking on the file does not expand its name. STEPS TO REPRODUCE 1. Create a file on the desktop with a large name OBSERVED RESULT The name will be truncated and cannot be read completely SOFTWARE/OS VERSIONS Operating System: Arch Linux KDE Plasma Version: 5.21.0 KDE Frameworks Version: 5.79.0 Qt Version: 5.15.2 Kernel Version: 5.11.0-arch1-1 OS Type: 64-bit Graphics Platform: X11 ADDITIONAL INFORMATION The Desktop Dashboard component is only available at https://bugs.kde.org/describecomponents.cgi?product=plasmashell. As I am submitting this bug report, this same component is not available in the selection menu. I decided to select this one because it seems to me that the maintainer is the same.
You can manually increase the amount of space available for labels in the desktop settings window > Icons page. But it's true that when text is elided, there's no way to see more without changing those settings, which is not a super great UX.

Git commit d191d5c535ab0f56a8266084f77196d84ee326d4 by Nate Graham. Committed on 14/01/2022 at 05:14. Pushed by ngraham into branch 'master'. folder view: always show tooltips for items with elided text The "Tooltips" feature is disabled by default, but it can be handy for items whose text has been elided, since otherwise there's no way to see the full text. So let's show the tooltip for such items even when the feature is disabled.

On Plasma 5.26 beta the tooltip only appears if 'Display informational tooltips on mouse hover' is checked in General Behavior KCM. Is this expected after this fix?
I suppose so, because it's a tooltip, so it respects the global "I hate tooltips, never show them" killswitch. That's what that setting effectively is.
