waves generate at double the intended amplitude

[stststephen]

I'm running Processing 4.4.4.

XYScope seems to be generating all the waves at double the amplitude. So for example, the "Calibration" circle appears like this:

As you can see, only the upper left quadrant is displayed within the path limits. Adjusting the volume output on my interface further proves that the amplitude problem is on the software end.

I'm temporarily fixing this by cutting all the draw settings in half, so for example a circle that's centered in the screen needs to be programmed as:
xy.circle(width/4, height/4, width/2);

Another temporary fix I found was to change the amplifier settings using
xy.amp(0.1);

but I don't think this is fixing the underlying problem, seeing as the circle is being drawn off-center:

Any ideas on how I can resolve this?

@stststephen That looks like a bug in the Processing IDE... I've been using 4.3, which is now a bit old.. just downloaded the latest (4.4.6) and saw the bug... downloaded 4.4.1 and no issue.. process of elimination to see what changed when that breaks a bunch of the examples... 4.4.3 has the issue... 4.4.2 = no problem (although the alphabetical order of example contributed libraries is mixed up)... sooo something was introduced in 4.4.3. Will create an issue there about it now..

Hi @stststephen and @ffd8 I suspect it is the introduction of matching the pixelDensity() to the default of the display you are using. So since 4.4.3 a sketch will be pixelDensity = 2 on a MacBook by default for example. Please check if adding pixelDensity(1) to the setup will solve the issue

Just tested it locally and that seems to fix it for now, not sure what the underlying issue is and wether or not it is something we need to solve internally or with the library
