Large grey border around gnome-terminal shadows when transparency is enabled (wayland)

Bug Description

I have found that after switching from Xorg to Wayland on Ubuntu GNOME 16.10 with GNOME 3.22, that there is a large strange grey border around the window:

- Fullscreen_gnome-terminal_in_AO_no_strange_border.png
- Fullscreen_gnome-terminal_window.png
- gnome-terminal_in_AO_strange_border.png
- gnome-terminal_window_strange_border.png

But this only occurs when the window is not fullscreen, and when transparency is enabled. Turning transparency off immediately fixes the issue.

By the way, gnome-terminal upstream doesn't support transparency since a few years. Some distros have patched it back in.

Yes, I know, I was thinking about that... So could it be an issue with the way it was patched in?

Jeremy Bicha (jbicha) wrote :

I'm curious whether this works on Fedora 25. Fedora also has a patch for gnome-terminal transparency but I believe their patch is different. Do you want to try to reproduce the bug there and report back here?

I have tested this on Fedora 25 and it works fine. No strange border or anything. So it's probably our patch then or its handling.

I can confirm this issue still happens in Ubuntu GNOME 17.04, with GNOME Terminal 3.20.2.

I can confirm this is happening in Ubuntu Gnome 17.04.

Juan, where did you get the theme you are using?

Fred (eldmannen+launchpad) wrote :

That looks like it could be the Arc theme.
In the repository as 'arc-theme'.

Jeremy Bicha (jbicha) wrote :

Thanks, Fred, but I want to know if he has installed an old version of the theme so I want to know where he got the theme from.

Thank you for taking the time to report this bug and helping to make Ubuntu better.

I am unable to duplicate this bug with the information provided. Please answer the following questions:

Could you check if this bug also affects Ubuntu 17.04?

What theme are you using and where did you get the theme from?

Does this bug affect all themes or just specific themes?

I use Ubuntu gnome 17.10 with theme United-gnome installed from its page. It affect all themes after the install and it have probably something to do with transparent panel enabled during theme installation.

Lech, do you experience this bug if you change your theme to Adwaita? or to Ambiance?

Yes, I have screen with adwaita. I think I'll experience it with ambience too, but I'm not on desktop atm.

Yes, I can duplicate this bug now. I don't normally enable transparency in my Terminal so I hadn't really experienced this earlier.

Can someone confirm that this is fixed with the latest gnome-terminal update in artful?

amano, this bug is still present in Ubuntu 17.10 Alpha "artful". This bug will be marked Fix Released when it's fixed.

May the patch gdk_window_set_background_rgba(gdk_window, transoarent) in gtk doesn't work under wayland when transparency is enabled? No problem under X with Unity though.

On Ubuntu 17.10, with wayland, looks like a very similar problem is still there. Should we open another ticket maybe?

@Robie, I run Arch now, so it would be best if someone else tested this, otherwise if nobody is around other than me to test it then I will happily do so in my QEMU VM. Just let me know if nobody gets back to you about this in a while.

This is fixed, sorry for the confusion; it's only linked to the SRU because it's a backport and I'd copied and pasted the merge changelog entry including bug reference.

Great news! Glad to hear it! I was surprised to see this issue still around.
