Indeed, the clicking action w/ trackpads (internal or external) have been an issue that got also raised with Support.
Check this thread, and see if the videos I included at the bottom match your description about the input inconsistencies.
If they match, would you mind adding your experience to that thread? The louder the feedback, I hope the quicker the fix will arrive.
My running, non-confirmed theory on this is, Roon is sharing its UI interaction code (to a degree) with the apps running on other devices that are primarily touch-based (tablets probably) and the “click” action might have been tweaked/weakened to a degree to not register accidental clicks on these devices, basically affecting desktop/laptop based input with it.
