    Snap applications

    With communitheme the snap applications Terminal, Calculator and System Monitor used transparency.
    They are now working on my Cosmic Cuttlefish installation. The transparency is gone. There are however some error messages.
    Code:
    Jun  2 07:59:58 pi-MS-7A34 gnome-calculato[14759]: Theme parsing error: gtk.css:2662:72: The :insensitive pseudo-class is deprecated. Use :disabled instead.
    Jun  2 08:01:08 pi-MS-7A34 gnome-terminal-[14909]: Theme parsing error: gtk.css:2662:72: The :insensitive pseudo-class is deprecated. Use :disabled instead.
    Jun  2 08:01:33 pi-MS-7A34 gnome-system-mo[14932]: Theme parsing error: gtk.css:2662:72: The :insensitive pseudo-class is deprecated. Use :disabled instead.
    It's not working on Ubuntu 18.04

    Re: Snap applications

    I think I'm seeing something different here.

    To clarify, the regular deb versions of the Calculator and System Monitor using Communitheme are working correctly in 18.10. But the snap versions are broken in that they are totally transparent and therefore unusable. I'm seeing this issue with Communitheme from both the stable and edge channels.

    Is there a snap version of gnome-terminal? I can't seem to find one.
    Code:
    paul@paul-VirtualBox:~$ snap install gnome-terminal
    error: snap "gnome-terminal" not found
    "snap search" doesn't find gnome-terminal either.

    Where are those errors being logged?

    I wonder if OP ran
    Code:
    env
    when first logged in would show anything helpful.
    I know if a wayland session is used then it dose not load Communitheme fast enough but a second login loads Communitheme fine.
    xorg session is fine though on my end.

    Re: Snap applications

    Thanks 1fallen, you prompted me to log into a Wayland session. Both the Calculator and System Monitor display correctly using Communitheme. It's Xorg that breaks those applications. I must remember to think Wayland more often.

    There's probably a lot on the Community Hub that I should be reading but the relevant threads are getting very long and I don't find the technical stuff re themes that interesting.

    PaulW2U did you then try to login to xorg from wayland, and was it any different?

    In an Xorg session, both applications are again transparent.

    Sounds like bug reporting time again.
    Thanks for checking PaulW2U.

    Re: Snap applications

    There is a bug report and discussion about the transparency
    https://github.com/ubuntu/gtk-communitheme/issues

    However on my installation of Cosmic with the 14.17 kernel the snap versions are working as intended.
    I am not able to check this further as my system crashed this morning.

    I'll take a look, thanks.

    I'm not sure I've reported back to you correctly now 1fallen. It's confusing having two supposedly identical calculators installed but from different sources and then having to work out which is which.

    So in a Wayland session I uninstalled both calculators. I installed the deb version and it was correctly themed with Communitheme. I uninstalled that and installed the snap version. No Communitheme but Ambiance. So it looks like Communitheme doesn't work at all with Wayland but makes the calculator totally transparent with Xorg. System Monitor also shows the same results but I can't start both versions at the same time.

    The attached screenshot shows my desktop when both calculators were installed.

    Perhaps someone who knows a little more than I do can confirm my revised findings?

    Yup that's my findings also on "wayland" but for me at least xorg session works fine I have Nvidia Drivers installed? I wonder if P-I H has Nvidia, I know he reports that kernel 4.17 is working for him.
    Hard to triage with this kind of information being reported. Maybe wait and see if Jbicha has anything to say.
