Ubuntu/Gnome 48 Beta + X11 + Nvidia 470: Black border obscuring edges of terminal window only when in X11 and not full screen.

[satmandu]

I'm not sure if this is a duplicate of #5660

I'm using the closed-source Nvidia 470 driver and ghostty 1.1.2, and my terminal edges are obscured by a black border.

I have not touched the default configuration.

The borders stop obscuring the edges of the terminal when I go full screen.

Anything else I can share to help debug this?

Can you try building a debug version from source? It looks like you've installed a version that was compiled with older GTK/libadwaita versions than are in the 48 beta.

For what it is worth, there is no change in appearance or this behavior with a rebuild against the current Gnome 48 Beta libraries:

ghostty --version
Ghostty 1.1.2

Version
  - version: 1.1.2
  - channel: stable
Build Config
  - Zig version: 0.13.0
  - build mode : builtin.OptimizeMode.ReleaseFast
  - app runtime: apprt.Runtime.gtk
  - font engine: font.main.Backend.fontconfig_freetype
  - renderer   : renderer.OpenGL
  - libxev     : main.Backend.io_uring
  - desktop env: gnome
  - GTK version:
    build      : 4.17.4
    runtime    : 4.17.4
  - libadwaita : enabled
    build      : 1.7.beta
    runtime    : 1.7.0
  - libX11     : enabled
  - libwayland : enabled

Curiously, running this over X forwarding via ssh doesn't cause any issues. The border doesn't obscure anything!

Is there something about X11 tunneling over ssh that makes for different behavior?

Running over X11 over ssh (no overlapping border - normal expected behavior):

The only other data point I have is that I'm running the Nvidia 470 drivers with the xserver it comes with.

Running ghostty over ssh to localhost does have the problem!

Shot in the dark, but does putting

window-padding-x = 0
window-padding-y = 0

in your Ghostty configuration change anything?

[satmandu]

That's the first thing I tried. No change, sadly.

[satmandu]

Here's another data point:

Setting window-decoration = server does make the borders go away, but then I lose the menu button to reach Terminal Inspector, Open Configuration, etc

[satmandu]

Ok here's another data point.
I can put this into ~/.config/gtk-4.0/gtk.css as per https://www.reddit.com/r/linux/comments/r91aqy/libawaita_makes_programs_look_terrible/hn9atbi/ and that appears to work around the issue:

window.csd {
    border-radius: 0px;
    box-shadow: none;
}

So is this a gtk or libadwaita bug then? Which project should I file a bug against?

[satmandu]

The minimal configuration I need in ~/.config/gtk-4.0/gtk.css to fix the issue is:

window.csd {
    border-radius: 0px;
}

[satmandu]

Setting that to:

window.csd {
    border-radius: 2px;
}

The border isn't too bad.

With the border-radius increased to 15, I replicated my issue:

[satmandu]

Ok this could be an OpenGL issue connected to the Nvidia drivers.

Multiple threads like this come up when I look further into this:

[satmandu]

I opened an upstream gtk issue: https://gitlab.gnome.org/GNOME/gtk/-/issues/7365

[satmandu]

Looks like I'm also seeing this with the open source noveau drivers in wayland after I resume from sleep:
