Comparison

Here is a side by side comparison of both tkinter turtle-graphics examples windows, with and without the GUI fix. Maybe the screenshot was reduced by me so that the difference was not obvious, but actually before the text was also blurry. Also the sizes are different. Increasing pixel density while not changing the number of pixels will result in smaller window sizes.

Solution

The solution is simple

Copyhttps://github.com/python/cpython/blob/main/Lib/idlelib/pyshell.py#L16-L22 tohttps://github.com/python/cpython/blob/main/Lib/turtledemo/__main__.py

Seehttps://learn.microsoft.com/en-us/windows/win32/api/shellscalingapi/ne-shellscalingapi-process_dpi_awareness

Has this already been discussed elsewhere?

This is a minor feature, which does not need previous discussion elsewhere
