SUMMARY When I click, ctrl+click, or shift-click on an icon on the desktop, or when I draw a rectangle to select a few, there is no visual feedback whatsoever. No icon is highlighted as selected. It looks as if the desktop wasn't even responding. The files are actually selected, though. STEPS TO REPRODUCE 1. click on in icon on the desktop 2. ctrl+click on another one 3. EXPECTED RESULT Both should be highlighted as selected OBSERVED RESULT They are not. However, if you press the mouse button without releasing it over one of them and start to drag, both will become selected and you will drag both, revealing that they were actually selected. STEPS TO REPRODUCE 1. place the mouse cursor on an empty area of the desktop 2. PRess the left mouse button and hold it 3. drag as if to draw a rectangle, encompassing a few icons on the desktop 4. release the mouse button EXPECTED RESULT While drawing the rectangle, you should see the rectangle. After releasing the mouse button, you should see the icons you had selected highlighted as such OBSERVED RESULT Nothing, as if this was not working. However, again, if you click and drag one of the icons you invisibly selected, it will become clear all of them were.

This is strange, I can't reproduce this either, but there is an option in the folder view settings about adding selection markers that does nothing for me. Can you check if it is selected in configure desktop -> icons -> features?
A bunch of things weren't working in that session (which if I remember correctly was the first one after installing Plasma) https://bugs.kde.org/show_bug.cgi?id=424419 https://bugs.kde.org/show_bug.cgi?id=424421 All issues were gone after reboot.
Oh good. :)
