dftfringe needs to work on Dale's 250% scaled screen and 100% scaled screens. QT6 will greatly help this

[gr5]

QT6 changes how dftfringe looks and that's probably a good thing. Here's a screenshot with QT5 compiled on the left and QT6 compiled on the right of the same basecode (current master branch morning of 12/3/2025).

Screen is set for 200% scaling on a 2560 pixel wide screen.

Note that with the QT6 code everything is doubled in size. As I believe you would want with 200% scaling.

I haven't wrapped my head around this yet and what needs to be done but what I think it means is that we can make the app look good on a 1280 screen at 100% scaling and it will look the same on a 3200 pixel wide screen at 250% scaling (and vice versa). In the past I found that 1280 was the absolute minimum app width for it to be reasonably useable.

Dale what is your screen width again?

Dale uses a 17" screen at 250% scaling with double pixels in each direction.

This means with Qt6 : If you have a standard 17" 1080p and use 125% scaling it will look same as with Dale screen.

I have written it in other issues. You might want to copy this somewhere as it will probably be useful for coming months.
