mouseWheel() not working when using FX2D renderer

[biggestpleb]

When using the FX2D renderer mouseWheel() is not called when the mouse wheel is moved.

void setup() {
  size(100, 100, FX2D);
}

void draw() {} 

void mouseWheel(MouseEvent event) {
  float e = event.getCount();
  println(e);
}

The other mouse functions (mousePressed(), mouseReleased() etc.) all work fine. The above sample code works if the renderer is changed to anything other than FX2D.

(Win 8 64bit)

Can confirm this for OSX 10.11.1, Processing 3.0.1.

(both with trackpad on retina and wireless mouse with scroll wheel)

In Windows 10 x64, also not working.
Also not working mouse buttons:
left and right buttons have one event.
Processing 3.2.2, Processing 3.2.3

This is still a problem in the latest release(3.3.5) any work around for this?
It behaves differently when FX2D is used (event.getCount() returns zero a lot while the scroll is being used and then some times suddenly jumps to -2 or 2) and when it is not (event.getCount() returns 1 or -1 consistently if you are scrolling up or down)

I am having an similar issue in release 3.3.4 on macOS 10.14.5.
event.getCount() returns a lot of zeros and some ones while scrolling slowly.
When I'm scrolling faster it suddenly returns high numbers in the range from 6-12.
