FX2D changing the result of MouseEvent.getButton() for mouse releases, is there a quick workaround?

San

In P2D this prints out 37 for the left mouse and 39 for the right mouse, but in FX2D it returns 0 for both (unless you release while holding the other mouse button down, then it outputs the number for the one still held down).

Mouse presses work fine, but is there a different way to get the released mouse button in FX2D?

There's no need for MouseEvent nor its getButton() method. ;;)
Just use mouseButton variable: https://Processing.org/reference/mouseButton.html

But it seems like mouseReleased() isn't working correctly for renderer FX2D: :-SS

So you should warn the devs about it: #:-S

The mouseButton global variable also just returns 0 for left and right in FX2D.
