Related Issue: #5047
Discussion: #4664
### Investigation
The behavior of iTerm mentioned on the Discussion thread was as follows:
- `cmd + u` can be used to toggle "Use Transparency"
- The "Use Transparency" toggle operates on a per-surface basis
- The "Use Transparency" state persists even after reloading the config
### Summary
Based on the investigation and discussions in the preceding pull
requests, this implements the `toggle_background_opacity` keybind action
for macOS with the following specifications:
- Switches background opacity on a per-surface basis
- The background opacity state persists even after reloading the config
- Background opacity switching functionality is also available in Quick
Terminal
- Does nothing if `background-opacity` is set to 1 or higher
- Does nothing if in fullscreen mode
### Verification
This functionality has been tested across following scenarios,
confirming correct action behavior for:
- Split Window
- Each split window maintains synchronized background opacity states
- Tab Group
- Background opacity states do not synchronize between tabs
- Quick Terminal
- Background opacity states remain synchronized even when windows are
closed
- Command Palette

This pull request was made with assistance from Claude Code.
I reviewed all AI-generated code and wrote the final output manually.

This PR fixes an issue #9563 where relative file paths were not being
resolved against the terminal’s current working directory before
opening.
#### Verification
Tested with directories containing:
```
/tmp/test/test
❯ du -h .
0B ./spaces-end
0B ./with dot.
0B ./space middle
8.0K .
```
Parent directory resolution also works as expected:
```
/tmp/test/test
❯ du -h ..
0B ../test/spaces-end
0B ../test/with dot.
0B ../test/space middle
8.0K ../test
16K ..
```

In your original description you mentioned that “Links should work for all situations as they do in iTerm2.”
I noticed that, for example, when running `ls`, the paths are not clickable, while they are clickable in iTerm2.
If you think this case should also be handled, I can open a separate PR for it once this one is accepted.
Implements #8399.
I didn't save `position` in this pr, since I don't see its necessity.
Changing `quick-terminal-position` requires a relaunch; saving and
restoring this would have to deal with conflicts. I also don't see why a
user would change this frequently.

This adds a couple optimizations to our CI:
1. macOS matrix gone, only test that freetype builds in addition to
Coretext.
2. Move Flatpak out to a triggered build on main similar to snaps. This
was our longest build and avoiding it in PRs is a win since it rarely
fails.
This changes our GHA that updates our color schemes to also upload it to
our dependency mirror at the same time. This prevents issues where the
upstream disappears, which we've had many times.
This disables a bunch of configurations that we don't need to actually
test for. The main one we want to keep building is Freetype because we
sometimes use this to compare behaviors, but Coretext is the default.
This is one of the primary drivers of CI CPU time.

I had a bit of the same annoyance as #9064. I agree that with balanced
padding, you should expect horizontal jitter when resizing horizontally,
and vertical jitter when resizing vertically. Diagonal jitter, however,
happened because the top padding was upper bounded by the left padding,
coupling the vertical and horizontal wobbling. This looks kind of janky,
and it's surprising that the balance between top and bottom padding
changes as you vary only the width of the window.
With this PR, the upper bound is instead equal to the maximum left
padding. Since this only depends on the config, not the current window
width, the diagonal wobbling is avoided. Both the top and left padding
still have the same range of motion as before.
An alternative could be to bound by the minimum or median left padding
instead. Open to suggestions.

## Description
This PR implements the basic functionality for "Liquid Glass" style
background support (#8155). I used OpenCode (Claude 4) in some capacity
to write this as I'm not super familiar with AppKit / SwiftUI. A good
chunk of this I still needed to write by hand since Claude doesn't
understand the Glass APIs, but I'm not 100% if the implementation here
makes the best decisions since the practices in Ghostty config and
separation of the AppKit code and SwiftUI seemed inconsistent to me.
Some of the combinations of options obviously create entirely unreadable
terminals, but I've found that regular glass and transparent with
opacity to be fairly readable. We *don't* enable this feature by default
since it would of course break existing users setups.
## Open Questions
- [x] How to determine the correct cornerRadius? For now this is
eyeballed, I can't see any macOS public API or clearly documented
constants.
- [x] Should boolean options be exposed for reasonable defaults?
- [x] Should the option need to be namespaced to macos-\*?

Reported by Mr. Hashimoto in discord.
These changes removedthe following warning:
`evaluation warning: 'system' has been renamed to/replaced by
'stdenv.hostPlatform.system'`
This adds a couple of Nix-based VM integration tests:
- Does `ghostty +version` run successfully?
- Can we create a new terminal window? (This is detected by setting the
background to a color that doesn't appear
normally on the desktop and seeing if we can detect that color in a
screenshot).
Obviously more can be done but I thought that these would be a couple of
good first steps.
The whole test suite can be run with `nix flake check`. Individual tests
can be run with a command like this:
```
nix run .#check.x86_64-linux.<test name>.driver
```
Bug: When toggling a Ghostty window between fullscreen and windowed mode
in the i3 window manager, or between tabbed mode and default tiling
mode, window borders would permanently stop being drawn around the
terminal window.
I bisected to find that the issue was first introduced in aa2dbe2.
The below explanation + the code in this PR was 100% generated by claude
code, since I don't know the first thing about x11 or terminal
development, and have never written any Zig before. I verified this code
change builds and solves the issue for me which I hope is more helpful
than just a bug report. If this code is actually garbage and the issue
should be fixed a different way it wouldn't shock me and this PR can
just be closed in favor of one from someone who knows what they're
doing.
Anyway this is the explanation that the llm generated:
Root cause was that syncAppearance() was updating X11 properties on
every call during window transitions, even when values hadn't changed.
These redundant property updates interfered with i3's border management.
The fix adds caching to syncBlur() and syncDecorations() to only update
X11 properties when values actually change, eliminating unnecessary
property changes during fullscreen transitions.
