Mouse cursor is different inside graphical windows of snaps (snaps not using system theme)

[Bruno Nova]

I noticed this in a Java Swing application I was packaging, and also on the ubuntu-calculator-app snap.

When moving the mouse cursor over the windows of those snaps, the cursor theme is different (black cursor instead of a white cursor).
This doesn't happen in the tic-tac-toe snap, though.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Leon (leonbo)]

Happens too for for keepassxc (2.2.0) in the snap store.

[Luis Alberto Pabón (copong)]

Happens as well to Wavebox.

[Sebastien Bacher (seb128)]

What Ubuntu version and desktop session do you use?

[J. Snow (jon.snow)]

Same here with chromium Version 62.0.3202.94 (Official Build) (64-bit). Xorg Ubuntu 17.10

[Yassine (yassine10suno)]

Happens for Mailspring as well

[Justin Nichols (jnichols21)]

Happens with Mailspring and Cumulonimbus.

[Anton Maminov (mamantoha)]

Happens with Mailspring and Gitter. Both are Electron applications.

Polarr chose to use Snap in part because it works cross platform, but the version in the AUR is not a Snap because the Snap doesn't match the system theme. We were contacted by the Arch community maintainer Kisuke-CZE seeking to fix this. To quote his comment at https://aur.archlinux.org/packages/polarr/#comment-629750:

"Unfortunately snap version is poorly integrated with my DE in Arch. So I decided to convert that snap package to standard ArchLinux package which I now published. Hope this PKGBUILD will work for you as well. (I am not sure with the link for downloading package, but worked for me on two diferrent computers)"

[Gaston M. Tonietti (gaston-tonietti)]

Also happens with Spotify client

[Sebastien Bacher (seb128)]

The issue was fixed in the desktop launcher for snap using the gnome runtime by that commit
https://github.com/Ubuntu/snapcraft-desktop-helpers/commit/4008601d

that's not a solution for other snaps by can be used as a trick until snapd properly solves the issue

[J. Snow (jon.snow)]

I confirm that the problem is solved in some recent snaps (chromium) but not in all of them (spotify).

[Eimis (eimantas-es)]

Bug affects me too on Ubuntu 18.04, skype, discord, simplenote, spotify, discord, all of these snap packages installed via software center are affected.

[Ian (nullbite)]

This bug also affects me on Kubuntu 18.04 (installed through `apt-get install kubuntu-desktop` on Ubuntu 18.04) in the Telegram desktop client.

[c_kharish (goodburner)]

Bug still present in 18.04.1, VLC & Telegram are some of the applications that are affected. Both are snap packages.

[Mustapha Hadid (mhadidg)]

This bug also affects me on Ubuntu 18.04.1 LTS.
Out of five snaps I've installed, two of them are affected: lepton and postman.

[Ben Landvatter (enzofromwb)]

I can also confirm this problem, still an issue today, 9.19
While using Thunderbird 0 (installed with snap)
and Tusk.

[Rachid (lafriakh)]

This bug also effects me on Ubuntu 18.04.1 LTS.
In spotify, postman, Skype..., All the snap apps.

[Oleg (krivorot-oleg)]

Ubuntu 18.04.1 LTS
telegram-desktop - confirm this bug

[Jonatã Bolzan Loss (jbopen)]

It is happening on Chromium Version 70.0.3538.67 (Official Build) snap (64-bit) on Ubuntu 18.10

[Marco Giannini (marco-giannini)]

Same problem with Telegram from snap on Ubuntu 18.10 (64-bit)

[Mattia Orlandi (void97)]

I have the same problem with mailspring, telegram-desktop, spotify and musescore. The ones installed with classic confinement (skype, android-studio, eclipse, vscode and atom) are not affected by this issue. I run KDE Neon 5.14.80.

[Andrea Pivetta (vanpivix)]

On Fedora 29, on telegram-desktop the cursor seems the same but it's smaller in the snap window.

[Marco Giannini (marco-giannini)]

The bug is still present on telegram desktop on Ubuntu 18.10

[Ryan Kennedy (ryaninvents)]

Has anyone found a good workaround for this issue? Seeing it on Ubuntu 18.10 with the Spotify snap.

[RedRaven (ravenmander)]

I have this bug on Ubuntu 18.10 in discord and gitkraken snaps. In addition there was no such problem with gitkraken on Ubuntu 18.04LTS.
I tried to run `export XCURSOR_PATH=$RUNTIME/usr/share/icons` in Terminal as suggested above but that doesn't help.

[osa (myxaosa)]

Still present on telegram-desktop on Ubuntu 18.04.1
Changes cursor theme

[Marv (marv.dj)]

Running Kubuntu 18.10.

Happens on all snap-app-GUIs. Completely ruins the snaps. Should be treated as top priority.
Furthermore it doesn adopt the native font and its size which further enhances the oddness..

[Sam (samr28)]

Kubuntu 18.04

Also experiencing this issue with some Electron snap apps.

Works fine: Slack
Different cursors: Mailspring, Discord, Telegram

[ZeryOs (zeryos)]

Ubuntu 18.04 -
Also experiencing this issue in Telegram Desktop.

[Darren (darren780)]

Also affected by this bug. Due to running at a 4k resolution, the cursor becomes difficult when moving across snap applications (size decrease).

[ZeryOs (zeryos)]

Also happens with Rambox snap.

[Toby Jones (catlover1019)]

I had this problem in some apps, and was able to work around it by changing the inherit in /usr/share/icons/default/index.theme to my preferred cursor.

[ichii (ichi-i)]

I am experiencing this in Electron applications installed via snap:
- Telegram
- Spotify
- Bitwarden

And also this non-snap app: Discord.

Could this be an Electron issue rather than snap?

[Thomas Iguchi (its-a-me)]

I think ichii is right. I just switched Mailspring from Snap version to regular Debian package and the mouse cursor is still too small. This must be an Electron bug.

[John Lenton (chipaca)]

There are (at least) two aspects to this:

1. people are always going to be able to use themes that are not available to snapped apps. This one we can't fix, but we do have plans to add "theme" snaps. Not really a snapd issue, although some support to make things automagic might be needed.

2. some snaps that could use themes haven't taken the extra steps to do so. Again not a snapd issue, although we are encouraging people to do this work (and have tried to make it as simple as possible).

I'm setting the bug to Invalid for snapd, which doesn't mean the bug itself is invalid -- it's just not something that snapd itself can fix.

[motang (mohan-ram)]

This happens with many applications that are snaps (Simplenote, Spotify, Chromium, Brave, Firefox) on Kubuntu.

[Jairo Mejia (jairo-mejia-2708)]

I am using Ubuntu 20.04 LTS and the problem is still there in different apps using SNAP to install it. As far as I know the struggling apps are: Spotify, Chromium, Mailspring, Postman, VLC and Octave. Not every app seems to have the problem the apps that I have installed without problem was: Audacity, Intelijj IDEA, GIMP, LibreOffice, Skype, DrawIO, KdenLive and VSCode.

I hope you can find a sooner solution, it seems careless but if you have a HiDPI display, the cursos is almost invisible.

[Dmitry Me (4x1md)]

I see this issue in Chromium under Ubuntu 20.04 LTS. It's weird because my calendar shows year 2020 and not 1980 with Windows 0.1 beta.

[Carlos Alberto Sierra Torres (darknemesisx)]

Se me presenta el mismo problema dentro de telegram de la snap en ubuntu 20.04

[Jānis Kārlis Kriķis (delfininsjezus)]

Happens to me aswell. Ubuntu 20.04 discord changes the mouse cursor.

[Einstein (hieu19926)]

Ubuntu 20.04 64bit with Apache NetBeans IDE 12.0 same issue :((

[Max Barry (max-maxbarry)]

Happens to me with Chromium and Discord snaps BUT ONLY if I start them quickly after system startup. If I wait at least ~15 seconds, or quit & restart the app, they display with normal correct system pointer/cursor.

[nolemretaW (nolemretaw)]

Still present in Discord, Spotify and Caprine (Facebook Messenger client)

[Velan Chandrasekar (untamed1337)]

This issue is still present in Telegram Desktop (snap package) in Ubuntu 20.04 LTS (Focal Fossa).
Not sure if this is with everyone.. but, the mouse pointer is a black hand, when pointed in the list of groups area & a black arrow, when pointed in the messaging area.

(Personal opinion: I believe it is these kind of petty things (ex. (esp.) LibreOffice imperfections/inconsistencies) why Windows users (desktop) are reluctant to switch to Linux. And, how & why MS managed to build a distro on its own)

[Rene Horn (rhorncnx)]

I just upgraded to 21.10, and it affects the Firefox from Snap if FF isn't using the automatic system theme extension.
