Re: [fltk/fltk] 1.4.x:focus box drawing incorrectly on OSX (e.g. 10.10.15) at scales >100% (#192) ManoloFLTK Feb 21, 2021  
 

@greg: I can't reproduce here what you show and have a hard time understanding how a continuous
line can arise from this code:
line_style(FL_DOT);
rect(x, y, w, h);
line_style(FL_SOLID);

I get dotted lines scaled to a fractional factor in which some dots or some intervals are twice longer
than others. As Albrecht reports, scaling factors < 1 produce somewhat irregular patterns.
I'll try to make these dots more even as I did for GDI+ recently.

I confirm the default building option is the same with configure and CMake and uses bundled JPEG and PNG
libs and the system's zlib. But this shouldn't be related to focus box drawing.

I recommend to use the Pixie app to explore in detail such drawing patterns.
