We fixed the scaling of the drawings on screens with high pixel density. This has fixed several scaling-related bugs and ensured that the drawings are now properly displayed on Retina and 4K displays (the lines used to be semi-transparent and had a thickness of half a pixel, which made it harder to use these drawings, especially on several different devices). Because of this improvement, the thickness of the lines on the chart might have visually changed and the lines can now look differently. This behavior is expected, you can adjust the thickness of the lines in the chart or object settings. If the width of the line is equal to 1, you can change the transparency of the line to make it less bright.
We apologize for the inconvenience and appreciate your understanding.
