This has been an issue for a while and I can’t recall if I have reported it or it is already a known issue. It seems like something that shouldn’t be hard to address. The text showing heap used vs available heap is rendered in such a way that the letters are very puffy and jagged. Almost like any anti-aliasing that would be blending the edges has the alpha channel interpreted as a binary 0% or 100% opacity. I’ve attached an image, not sure if it will are it through. I’m testing NB 11.3-beta 2 with JDK 13.0.2 on macOS 10.15.3 (beta)"
Eirik Bakke confirms that this has been an issue for a long time. In particular, the memory gauge should be updated to look good on HiDPI/Retina displays.
