snap-store launches without theme (transparent) when using non standard themes

[fcole90]

Version 20200312.57b777d 294 - latest/edge
Ubuntu 20.04

If I launch the snap-store when using a custom theme, probably one not included in the themes snap, the app looks "transparent". I mean that I can see the banners and the icons of the apps, but the buttons and background is fully transparent, I can see what lies in the window behind.

What happens:
no theme loaded when a custom theme is in use, causing transparent app not being usable

What I would expect:
app to fallback to some default theme (possibly Adwaita or Yaru)

[Erich Eickmeyer (eeickmeyer)]

This seems to be affecting users using themes that are not included in the gtk-common-themes snap. When this happens, the snap-store snap should fall-back to using Adwaita, but in this case, it is not.

[Ken VanDine (ken-vandine)]

The current issue was fixed by adding some more themes to gtk-common-themes. Soon we'll have the ability to auto-install gtk themes that are missing.

I confirm that this is fixed atleast when you use snap-store from the beta channel. Which was updated today and it is at version 429.

If you want switch to that channel either from Snap Store or with command:

snap switch snap-store --channel beta

[Michael (laughingman01)]

Still not fixed here

A discussion is mentioned here too: https://github.com/lassekongo83/zuki-themes/issues/160

[Mantas Kriaučiūnas (mantas)]

Bug isn't fixed - snap-store in Ubuntu 20.04 still launches without theme (transparent) when using lots of different themes, see bug #1886295

[fcole90 (fcole90)]

Hi Mantas, if this is still happening to you, I suggest you open a new bug, it might be due to a different cause.

[Angel D. Segarra (angel-segarra)]

I have this problem on 20.04 and using Yaru, never used anything else.

[Angel D. Segarra (angel-segarra)]

Never mind, reboot fixed it. I noticed some else though, I have changed between the Yaru variants in System settings, if I change it from say Yaru to Yaru Dark, to Yaru Light and then back to Yaru, some things do not respect the theme change like system update, shows up as Yaru Light.

[J. McDonald (mcdonald-joseph)]

I'm using Xubuntu 18.04 and Snap launches with no theme (transparent window). I am using the standard Xubuntu theme. I have also tried other installed themes (Greybird and variations) and it still does not work. In fact, I cannot find a standard theme in Xubuntu that does not result in a transparent window for Snap.

[Sebastien Bacher (seb128)]

Reopening since that's still an issue, it's not specific to the store, any gtk software has the issue when it doesn't have permissions to read the gtk.css, which happens in this case because it tries to open the one under /var/lib/snapd/hostfs/usr/share/themes (which the snaps is adding to XDG_DATA_DIRS)

[James Henstridge (jamesh)]

Some notes from a conversation on this issue:

Rather than adding /var/lib/snapd/hostfs/usr/share to XDG_DATA_DIRS, it would be better to add some other directory the snap controls to XDG_DATA_DIRS, and symlink in the data directories from hostfs that we are actually interested in (probably metainfo and maybe applications?). This would prevent unexpected data changing the behaviour of the snap.

While the symlinks are likely to be static, we probably can't bake it into the snap since Snapcraft and/or review-tools will complain about dangling symlinks pointing outside of the snap. Instead, a command-chain script could set up the directory and symlinks under $SNAP_USER_DATA or $SNAP_USER_COMMON. The command chain script could even do the $XDG_DATA_DIRS modification before chaining to the real executable.

[Sebastien Bacher (seb128)]

The issue should be fixed in the edge channel now
