I am also getting noise on channel 2. It should be a triangular wave. I just have 3 resistors in series. the first one is a current limiter. the second one is the load. and the third one is a current sensing resistor, 330 ohms,load resistor and 1 ohm resistor.
Source voltage is a triangular wave on channel 1. Channel 2 should look similar but has noise which messes up the xy plot screen. this was to be a simple component tester. The load is the component under test. resistor, capacitor etc. have different shape curves by type and whether they are good or bad.
The readline/ read integer errors do not affect measurements in any way. Can you share a screenshot of the noise ?
zoomed in on the waveform
The voltage on channel 2 peak to peak is less than 10mv. The 12bit ADC gives a resolution of 1.4mV LSB . So in your screenshot you have about 4 bits worth of data. A few bits of noise will always be present on top of that data.
If this is indeed what you are trying to measure, the adalm2000 is not the tool to measure that. If not I would recheck the connections / computations.
No bug here in my opinion.

Here is another screenshot; hard to get a good trigger
I can increase the current measuring resistor from one ohm to 10; I will try that and post the new waveform.
You can also check out this post - https://ez.analog.com/studentzone/f/q-a/118735/adalm1000-adalm2000-current-and-voltage-measure-resolution
I increased the current measuring resistor to 11 ohms. The input signal to the test resistor then dropped somewhat and now has gliltches on it. I adjusted the gain for channel 1 and 2 somewhat.
I increased the input waveform to 10V and it made a difference on the oscilloscope display. I can't use that since it would possibly fry some digital chips.
I would have expected the adalm2000 to have some builtin amplifiers. Next model they should add that.
