Is your feature request related to a problem? Please describe.
Borders have quite a bit of visible aliasing on the rounded window corners of Windows 11.

Describe the solution you'd like
Implementing anti-aliasing for these borders would make them look significantly better.

Additional context
PowerToys did this with always-on-top borders in their latest update. I'm not sure how related, if at all, their border code is to Komorebi's, but maybe it helps :)

I honestly don't see anything 😅 But I have a friend who is very serious about aliasing and hinting and all those things, so I know if you see it you can't stop seeing it.

I'll leave this open for someone else, I honestly wouldn't even have any idea where to start since it looks like they are drawing borders in a completely different way using Direct2D directly.

I see this problem on my pc.

I don't know Rust but I found that you are using windows::Win32::Graphics::Gdi::RoundRect. Maybe it is enough to enable antialiasing in general. I found those sources about that:

Could you look and check if that may help?

Site Note: I found that some fonts have antialiasing issue as well.

Some good progress has been made on anti-aliasing which testers can try on the feature/tacky-borders branch.

@LGUG2Z could you create binaries from mentioned branch?

The binaries are built and uploaded automatically by GitHub Actions: click the green tick next to a commit and it should take you to the Actions run where the commit was built and the binaries were uploaded.

I did few tests and looks like border around window looks better. Is it possible to the same for rounded stack?
On my screen stackback looks as follow:
