When gtk2 libraries are in use and the system text is scaled (in my case by a 1.25 factor) images rendered on DrRacket appear distorted, with blurred borders or tearing as in this picture:
https://imagebin.ca/v/3bO6ry0vaXzL It is an artifact. The circle was generated via `2htdp/image`. I'm barely familiar with the underlying `racket/draw`, but I can reproduce the same result with this more low-level code: (define target (make-bitmap 400 400)) (define dc (new bitmap-dc% [bitmap target])) (make-object image-snip% target) (send dc set-pen "blue" 1 'solid) (send dc set-smoothing 'aligned) (send dc draw-ellipse 0 0 400 400) At first glance it is not hardware-related since I get the same result in different computers with different processors and graphic cards, one where the last gtk3 libraries are probably not installed and the another one where I call drracket with `PLT_GTK2` enabled. Interestingly, the artifact disappears if I apply `make-screen-bitmap` instead of `make-bitmap` in the first line. I wonder whether this kind of artifact or the code that triggers it may have something to do with the issue discussed here: https://groups.google.com/forum/#!topic/racket-users/6dIb242Ve8s -- You received this message because you are subscribed to the Google Groups "Racket Users" group.
