Starting snap-store all the characters in the window are crumbled.

The settings we're failing to get on impish are:

  org.gnome.desktop.interface font-antialiasing
  org.gnome.desktop.interface font-hinting
  org.gnome.desktop.interface font-rgba-order

They're notable because they moved some time ago from:

  org.gnome.settings-daemon.plugins.xsettings antialiasing
  org.gnome.settings-daemon.plugins.xsettings hinting
  org.gnome.settings-daemon.plugins.xsettings rgba-order

which is still used on focal.

This seems to also affect other snaps like firefox - so I don't think this bug should be filed against snap-store-desktop - and similarly, if you install the font-manager deb in impish, this crashes on startup with:

(font-manager:227159): GLib-GIO-ERROR **: 16:12:07.589: Settings schema 'org.gnome.settings-daemon.plugins.xsettings' does not contain a key named 'antialiasing'

So I feel like there are some more systemic issues going on with the changes to these gsettings paths for font settings in impish.

[Alex Murray (alexmurray)]

I have reported the font-manager crash in https://bugs.launchpad.net/ubuntu/+source/font-manager/+bug/1937993 which is private for now whilst waiting for the retracer to try and retrace from the attached coredump.

[Daniel van Vugt (vanvugt)]

Yes I was just waiting for confirmation that it was a common GTK-in-snaps problem. Looks like it would be.

[corrado venturini (corradoventu)]

Seems same problem: https://bugs.launchpad.net/ubuntu/+source/gnome-tweaks/+bug/1935569

[Sebastien Bacher (seb128)]

The issue seems to be resolved with the recent snap update, could people refresh and try again?

[corrado venturini (corradoventu)]

Resolved with snap-store 40.0-341-gb49ac9c 549
thanks

[Daniel van Vugt (vanvugt)]

Yeah I went hunting for this bug while ISO testing last night and could not find it.

[Kristof Bernaert (vanbernaert)]

I have this same problem in a lot of other applications too, like Inkscape here on screenshot example.

[Daniel van Vugt (vanvugt)]

Please report the Inkscape issue to https://gitlab.com/inkscape/inbox/-/issues

[Kristof Bernaert (vanbernaert)]

This needs to be resolved per application?
If yes I downgrade to v20 again.

[Daniel van Vugt (vanvugt)]

Snaps are self-contained with their own self-contained library bugs. The version of Ubuntu won't change that. But you should be able to avoid the issue by just avoiding the snap:

  sudo snap remove inkscape
  sudo apt install inkscape

[Kristof Bernaert (vanbernaert)]

Ow, Thanks a lot! that indeed resolves the problem. I need to read bit more what that 'snap' is doing. Not a newbie but neither an Ubuntu expert. But we make here with the company a 100% switch to opensource. It's not complicated, but this issue made us doubting.

[Daniel van Vugt (vanvugt)]

Was this actually fixed in a snap or is the above change by mistake?

[Daniel van Vugt (vanvugt)]

If anyone encounters this issue in Inkscape, please report it to https://gitlab.com/inkscape/inbox/-/issues first and then add a comment here.

[Angel D. Segarra (angel-segarra)]

Should the snap-store update be in stable already? The latest stable is 547 and has this problem.

[corrado venturini (corradoventu)]

on Ubuntu Jammy stable version is 554 and does NOT have the problem.

[Angel D. Segarra (angel-segarra)]

Should have specified, this is on 21.10 and snap is tracking latest/stable/ubuntu-21.10 which is 547

[corrado venturini (corradoventu)]

But You have also other versions:
channels:
  latest/stable: 3.38.0-64-g23c4c77 2021-06-15 (547) 53MB -
  latest/candidate: 3.31.1+git189.991d1d1d 2021-04-20 (539) 45MB -
  latest/beta: 3.38.0-66-gbd5b8f7 2021-11-12 (558) 56MB -
  latest/edge: 40.0-341-gb49ac9c 2021-09-20 (549) 48MB -
installed: 3.38.0-64-g23c4c77 (547) 53MB -
so You may try to refresh
snap refresh snap-store --edge
or
snap refresh snap-store --beta

[Angel D. Segarra (angel-segarra)]

Thanks but unfortunately I don't have that flexibility. The status was changed to fix released 2 months ago, so I guess my question is: when can we expect this to land on stable/ubuntu-21.10 ?

[Daniel van Vugt (vanvugt)]

The bug is indeed in both jammy and impish now. Seems to be a regression of a regression.

[corrado venturini (corradoventu)]

On my Jammy i had:
channels:
  latest/stable: 3.38.0-64-g23c4c77 2021-06-15 (547) 53MB -
  latest/candidate: 3.31.1+git189.991d1d1d 2021-04-20 (539) 45MB -
  latest/beta: 3.38.0-66-gbd5b8f7 2021-11-12 (558) 56MB -
  latest/edge: 40.0-341-gb49ac9c 2021-09-20 (549) 48MB -
installed: 3.38.0-64-g23c4c77 (547) 53MB -
corrado@corrado-n4-jj-1107:~$ snap refresh snap-store --beta
snap-store (beta) 3.38.0-66-gbd5b8f7 from Canonical✓ refreshed
corrado@corrado-n4-jj-1107:~$ snap refresh snap-store --edge
snap-store (edge) 40.0-341-gb49ac9c from Canonical✓ refreshed
corrado@corrado-n4-jj-1107:~$
I see the problem with version 547 (stable) and 558 (beta) but NOT with 549 (edge)

[Daniel van Vugt (vanvugt)]

Seems to be fixed in 558 on both jammy and impish today. If you have any problems with 558 then please open a new bug to avoid further confusion.

[corrado venturini (corradoventu)]

Confirm: NO PROBLEM with 558

[Kristijan Žic  (kristijan-zic)]

I can see this bug on Foliate and Inkscape. Can anyone tell definitely what the issue is and how to fix it?

I've created the issue for Inkscape here:
https://gitlab.com/inkscape/inbox/-/issues/5929

And the issue for Foliate here:
https://github.com/johnfactotum/foliate/issues/820

Now someone please help. :)

[PabloRQ (pablo-romeroquinteros)]

This bug still affects Inkscape (snap version 1.1.2-08b2f3d93c-2022-04-05 + Ubuntu 21.10).

The solution of uninstall the snap and install it with apt is not a real solution.

[Daniel van Vugt (vanvugt)]

The Inkscape issue is tracked in https://gitlab.com/inkscape/inkscape/-/issues/2971 and the latest comment says:
