Draw Pixel operation is unpredictable on macOS M1 with metal pipeline if [[point_size]] is not defined. Due to this unpredictability it is difficult to write an automated test.
I have developed a test which successfully detects this failure. It needs to be run with "-Dsun.java2d.uiScale=1.0". I will update the PR soon.
