Does C-h l view-lossage show something useful after an attempt to 
perform spellcheck? Is there anything in the *Message* buffer?

I could not suggest something in the case of wayland session, but if it 
is X11 then attempt to acquire key grab should fail if another 
application already set this shortcut. So you could try if e.g. 
xbindkeys would report a conflict if such keystroke is added to its 
config. I have never used it, but there is an interesting feature 
XF86LogGrabInfo:

Due to global shortcut emacs should lose focus for a moment and it 
should be noticeable. I would also check if xev reports expected key 
symbol. Just to be sure that $ is in its usual place yet.
