That could explain it. I have a MacBook Pro laptop with two external monitors
attached. The virtual machine display is on one of the external monitors. I
can imagine that a bug in the interaction between SDL2 and the virtual
graphics stuff could result in coordinates with large numbers as if the three
screens were one huge virtual display. I'll try it with the VM displayed on
just the laptop screen, and try with the external monitors unplugged to see if
it makes a difference. If that helps we can see if there is a way to get it to
work with external monitors.
Do have an idea what is different with the mouse when it is in a menu screen
and the magic wand mouse cursor does display and move correctly?
Thanks,
Sidney

A mouse event with so large numbers is discarded by Enigma on purpose,
because the black ball would suddenly be subjected to an enormous impulse,
if the mouse event would have been interpreted the normal way. So, the ball
not moving is a logical and necessary consequence to an overly large mouse
xrel/yrel-pairing. So ... we have to ask: Why does SDL2 report so large
xrel/yrel-values?
I cannot reproduce the bug ... could you please answer the following questions?
Do you use a special kind of mouse or mouse port?
Do you use an intermediary program (like a logger) or a remote desktop?
(Those might manipulate the mouse coordinates. The fact that you observe the
same problem using VirtualBox can be explained by (1) VirtualBox
manipulating the mouse coordinates or (2) the host OS being involved in the
bug.)
Were there other windows on the screen, besides Enigma's window?
There is a bug report about SDL 2 here concerning "jumpy" relative mouse motion:
https://bugzilla.libsdl.org/show_bug.cgi?id=3067
<https://bugzilla.libsdl.org/show_bug.cgi?id=3067>
It needs other windows other than Enigma to be present. It should be closed
on X11, but your host OS might still be reporting wrong numbers. However,
the numbers you report are so much larger, that it just doesn't make sense,
unless you use something like a 40.000 x 20.000 pixel display?

I tried installing on Ubuntu 20.04 based Linux Mint Mate and got the same
problem with the mouse while in the level.
At this point the only point of difference I see is that I'm running it
on a
VirtualBox virtual machine.
In other news, I've built and uploaded a macOS dmg that anyone can use to
install Enigma on macOS without having to have Homebrew and without
building
from source. So far it has only been tested on macOS Catalina. If it
doesn't
work on High Sierra or Mojave, let me know and I can build it on a High
Sierra
machine instead, which should be forward-compatible to Mojave and Catalina.
Big Sur will have to wait until I can set up a machine to play with it.
