VR to work on wayland fractional scaling issues

[and-rs]

What do you want to change?

hi. I want to work on this sharpness-related rendering issue described in this closed issue here: #1938 (Current state prevents ghostty from rendering sharply at fractional scaling in linux wayland because of a gtk/gdk API)

At some point the issue was regressed, I have been investigating the cause and drafting some successful fixes locally. So far I am missing testing but we'll get there eventually.

about me: I haven't done lots of OSS but I really like zig. I really like ghostty and would love it to be pixel perfect in linux just as it is in macos. I do use AI but I like doing things right and understanding what I generate with it.

thanks!!

Why do you want to make this change?

I believe fractional scaling and wayland are both common scenarios and even if the bug or symptom is sometimes barely noticeable it degrades the Ghostty experience on the Linux userbase.

I acknowledge that:

• I have read the Contributing Guide and understand the contribution process.
• I have read and agree to follow the AI Usage Policy.
• I wrote this vouch request myself, in my own voice, without AI generating it.
