> I believe the ugliness was caused by rendering the text + dropshadow into a buffer created with the 'nominal' pixel dimensions, then causing it to scale up a bit by drawing it on to the HiDPI screen (e.g. a 125% scale, which resulted in blockiness). As mentioned by David Green above it looks OK if the drop shadow effect is turned off. In this case text was drawn straight onto the Graphics2D.
Can confirm I disabled dropped shadow on macOS and it was acceptable. I also never liked the gradient so if by getting rid of it we clean up some complex code, even better. --emi On Fri, Feb 28, 2020 at 1:04 PM Peter Hull <[email protected]> wrote: > > On Fri, 28 Feb 2020 at 10:37, Tim Boudreau <[email protected]> wrote: > > I happened to be around to chat with the author of that code > Thanks for the info; I mentioned above that the code seemed strangely > complicated and I could not find any comments or history to explain > it. > > The reason: GradientPaint's allocate large rasters (large being int[width > > * height * 4]) on every repaint. > I did not know this.
