Transparency broken in 1.16 with gnome-shell

Mar01 commented 8 years ago

I am using the Gnome desktop environment on Arch Linux. The package is installed from the Arch community repository. All other packages are up to date.

After updating mate-terminal from 1.14 to 1.16 the ability to make the mate terminal window transparent does not work. The slider is there and functions but has no effect on the window; the window remains completely opaque. After downgrading back to 1.14 transparency returns just as I set it in my profile.

I apologize if this is a bug introduced by Arch and I'm in the wrong place, but I wouldn't know how to tell. This is actually my first bug report and I'm still getting a grasp on how the upstream/distribution stuff works.

I like my MATE terminal...

With mate-terminal-1.16 we switched to use gtk3. But i can't confirmed the issue with fedora 25 (gtk+-3.22.0) and f24 (gtk+-3.20) Transparency works well here. Which gtk3 version use rolling ArchLinux currently? Is there a reason why you don't file a report at your distro first? This is important to preclude that the issue isn't distro related :P

Mar01 commented 8 years ago

As far as I can tell, my Arch is using gtk3 version 3.20.9. (Actually, looking closer at it like I should have in the first place, it's marked out of date. That's probably why I having this problem. Duh.)

And as for why I didn't report it to Arch first: Because I'm inexperienced and uneducated in these matters, and a stupid idiot. All I know is I like the other changes 1.16 made and I still want my transparency durr!

I was reading the Arch wiki on reporting bugs and got the impression that they encourage upstream reporting, but I guess I should have thought about it more and bugged them in the forums instead of bugging you first huh? :)

Well thanks for wasting your time on me anyway, I do appreciate the reply. I'll come back when I'm not being a pest.

Erm, is this where I close the issue or should I leave it open for some reason?

raveit65 commented 8 years ago

Leave this report open until we know what causes the issue. Don't understand me wrong, first someone from us needs to confirm the issue otherwise it is impossible to fix it, if it is really a issue. And i'm using fedora , so i can't test it for ArchLinux. So a downstream report where the package maintainer can confirm it is helpful.

Works for me in LMDE 2 (GTK+ 3.14.5), Ubuntu 16.10 (GTK+ 3.20.9) and Debian Testing (GTK+ 3.21.5). Just in case - check whether you have compositing enabled in your window manager...

In the past I had same problem

Since I installed mate-tweak it works

raveit65 commented 8 years ago

Confirmed, with GTK3 we use RGBA Colors, so we need a compositor for the alpha channel. @Mar01 Please enable compositor with

gsettings set org.mate.Marco.general compositing-manager true

Than transparency should work.

"No such schema 'org.mate.Marco.general'" ?

Also installed mate-tweak from the Arch User Repository, still does not work.

"Just in case - check whether you have compositing enabled in your window manager..." I don't think it's possible to disable compositing in gnome 3...

on the preferences of mate tweak, go to windows, and choose marco (composition gpu with compton)

with this option, it works for me

If I choose marco (without composition), it doesn't works

The drop down is not clickable.

I think you're assuming I'm using the mate desktop. Just to clarify, I am using gnome shell 3.20.4.

raveit65 commented 8 years ago

This schema is from our window manager

I am using gnome shell 3.20.4.

Confirmed, no transparency with running 'mutter' in Mate session (f24). Weird, that it doesn't work with mutter as it is a WM with Compositor, as far i know. But gnome-terminal-3.20.2 have transparancy with mutter.

Anyway, i am not really sure if this will ever fixed, as no one use gnome-shell, sounds like a 'Can't Fix' for me.

PS: mate-tweak is only a gui for gsettings keys ;)

Mar01 commented 8 years ago

Blast! Guess I'm boned. Actually the reason I use the mate terminal over the gnome terminal is the gnome terminal won't do transparency, but you say it does? Maybe it's an Arch thing.

Guess I have to hang on to 1.14 for as long as I can.

sc0w commented 8 years ago

the question is, why it works with gtk2, and it doesn't work with gtk3 ?

ghost commented 7 years ago

It's not only gnome shell. I am running both xfce4 and i3 on the same Arch system with mate-terminal as my preferred terminal emulator. While transparency works well in xfce4, it doesn't work with i3. Downgrading to 1.14 fixed it. I guess It's sort of a deeper-lying problem than just gnome-shell after all.

You can find the dependencies for i3-wm here. (I got those by running pacman -lu i3-wm.) The dependencies of xfce4 as installed on my system can be found here. Finally here's what's used by i3 but not by xfce4:

xcb-util-cursor
xcb-util-renderutil
xcb-util-image
xcb-util-keysyms
xcb-util-wm
xcb-util-xrm
libev
yajl
libxkbcommon-x11

I guess this means the problem lies with one of the above. Maybe @Mar01 could check whether gnome-shell relies on any of these packages in his setup, so we can narrow it down further.
