I'm running a current version of Arch Linux (KDE) on a Dell laptop.
When I press the Meta key (with the Microsoft logo) it brings up the application launcher menu+. So it's not a dead key. And Ctrl works as expected.
However, Ctrl+Meta does not highlight the pointer / cursor position, nor does clicking the mouse animate anything, despite having both "Mouse Click Animation" and "Track Mouse" checked in the Systems Settings / Desktop Effects configuration, and confirming that the key binding for "Track Mouse" has both "Ctrl" and "Meta" checked.
I tried a variety of other finger-yoga contortions, but was unable to locate whatever magic combination would work.
Is there some common application or setting that might be overriding the above? (I don't believe I'm running anything especially peculiar enough to override KDE / Plasma.0

This is the settings screen:
Cursor is highlighted like this:
