cygwin install blurry on high dpi Windows 10

Hi,

My office laptop is Windows 10 with a high DPI display.

I found that the installer is blurry, especially inside the window. The
title of the window is clear.

Is this something that has been reported before? If nobody has reported it,
then I would like to report the issue here.

Attached is the screenshot of the installer to show clear title with blurry
content.

Thank you.

Thanks for reporting this issue.

This is Windows doing "dpi virtualization" (it reports 96 dpi to the 
app, and then upscales what it draws to the actual dpi)

Since we (now) use standard UI elements for everything in setup, it 
should 'just' be a case of marking setup as being able to handle being 
told the real dpi.

I built an updated setup with that change:

https://cygwin.com/setup/setup-2.904-4-gaa071e.x86_64.exe
https://cygwin.com/setup/setup-2.904-4-gaa071e.x86.exe

Perhaps you could try that and see if it improves things for you?

Looks fine for me, sharp as a knife. However, also the font size is a 
half-point smaller and looks quite spiddly, maybe you could make it a 
point larger?
Thanks

Do you mean change the font size everywhere?

I'm really not keen on that, as it probably means checking and adjusting 
the layout of every dialog (and then looks too small for those of us 
cavemen still using 96 dpi displays)

Thank you very much. I was waiting for this to happen.

No problem.

I can't fix problems I don't know about[*].

[*] this is not an undertaking to fix problems I do know about. :)

Thanks.

And of course, the logo is a different size, because it's drawn using an 
icon, not an image.

Hi Jon,

I tested the installer that you have provided, and the output is very sharp
and clear.

The installer functionality also works as expected.

I hope this version can be made into the official version.

Thank you.
