This does not happen on MacOS X on a standard, non HiDPI, display. The pointer is created like this : win.setPointerIcon(win.getScreen().getDisplay().createPointerIcon(new PixelRectangle.GenericPixelRect(format, new Dimension(width, height), width*4, true, buffer, hotx, hoty)) Thanks a lot for your help. 6174 1 sgothel 2019-03-30 06:17:10 +0100 I assume this is a NEWT Window.

If at all, the pointer bitmap should be presented smaller in high-dpi mode than expected, but this doesn't seem to be the case here. Therefor the NSCursor seems to be upscaled by OSX to be same size. some other discussions https://stackoverflow.com/questions/12021812/nscursor-images-on-a-retina-display Please reopen this bug if you can reproduce and provide a unit test for me to reproduce this issue.
