ViewsWhy is the Tkinter render quality much worse on windows?
I have developed a python app with Tkinter on a Mac. It involves forms, and canvas drawings. On the Mac, it looks great. However on my Dell laptop (4K display, and more powerful than my Mac), the Tkinter ui appears very pixelated and certain elements are located slightly differently. What is this problem known as and what can I do to render Tkinter better on Dell Windows 10 or other platforms in general? Here is a screen shot of the same part of the UI (showing form and canvas drawing)...
Windows(bad)
Mac(normal)

Antialiasing is only enabled for Tkinter canvas object in OSX . You can get the aggDraw lib: http://effbot.org/zone/tkinter-aggdraw.htm as a workaround, but otherwise you will get jagged lines when trying to draw on a canvas. Fonts however should be anti-aliased on all major platforms.

The differences in the display of the same application are due to differences in render engines used by each Operating system.
This is coverd in a Pakt pub ebook called Tkinter GUI Application Development Blueprints
passage regarding this topic available here.
It may be a pain to do but it looks like the most common fix for this is to detect your enviroment and write independent styles using the external option database more info is available in the documentation here.
