snap telegram-desktop=5.14.3 doesn't run in KUbuntu 25.04 #29332

ashl1 · 2025-05-19T09:28:49Z

Steps to reproduce

I've upgraded from previous stable snap version. Old version was worked but new one doesn't run.

This is not working:

Open telegram-desktop either from desktop or console

This is working:

snap run --shell telegram-desktop
export QT_QPA_PLATFORM=xcb
telegram-desktop

Expected behaviour

The app should open. Logs in console:

I don't have the possibility to test on each existing distro version out there but I can't reproduce on Ubuntu 24.04. I assume that's either a problem with your setup or a regression on Ubuntu side.

ashl1 · 2025-05-19T10:30:03Z

Yeap. I've updated to latest 25.04 Plucky recently. And updated telegram version after that.
As I understand Ubuntu 24.04 uses Gnome while I use KUbuntu (uses KDE) that might affect that.
Of course you don't have resources to test in all distros and setups. And the problem has a workaround so the priority might be lowered. I was teached that all errors should be reported, so I opened the ticket.
Anyway thanks for the reaction!

ilya-fedin · 2025-05-19T10:35:15Z

I'm not sure you've reported it to the right place, this looks like a Qt bug

Master811129 · 2025-05-19T12:22:06Z

I have the exact same issue kubuntu 25.04 and nvidia

While I have integrated AMD GPU (Ryzen 4700U). I think this might be KUbuntu specific. The strange behavior that previous snap stable version works perfectly in KUbuntu 25.04. The problem appears only after upgrading Telegram Desktop to the latest snap version

gonzalofarias · 2025-05-19T14:25:46Z

I have the same problem here. I'm using Kubuntu 25.04 and updated Telegram yesterday. It worked fine before that.

I have exact same issue at exact same circumstances. I downloaded latest github release linux binary v5.14.3 (not snap) and it work for me fine. Seems like this is snap specific.

benoitg · 2025-05-19T14:55:10Z

I have the exact same issue kubuntu 25.04 and intel GPU, wayland session. So it's not gpu specific either (nvidia and amd gpu were also reported above). Like others, it worked fine before the upgrade to 5.14.3 yesterday, and I have the same output as @Master811129. No upgrade to system packages at the same time, so it's not a recent upstream regression in kubuntu.

Same issue here after update snap to 5.14.3. 5.14.2 worked fine. KDE Neon, Wayland, Intel.
No KDE/distro packages were updated. So it's something KDE(Qt?)/snap/wayland specific

ilya-fedin · 2025-05-19T15:49:19Z

Are you sure you had 5.14.2? Snap version before 5.14.3 was 5.13.1.

adeptg · 2025-05-19T15:58:11Z

Are you sure you had 5.14.2? Snap version before 5.14.3 was 5.13.1.

Ah, yes, I'm sorry, my bad. The old version was 5.13.1

$ snap list --all telegram-desktop
Name Version Rev Tracking Publisher Notes
telegram-desktop 5.13.1 6597 latest/stable telegram-desktop✓ disabled
telegram-desktop 5.14.3 6639 latest/stable telegram-desktop✓ -

Also, the workaround @ashl1 provided works for me:

snap run --shell telegram-desktop
export QT_QPA_PLATFORM=xcb
telegram-desktop

soumyaDghosh · 2025-05-19T19:20:20Z

Same problem for me. I reverted to the last working revision,

If the snapshot is still in your pc then you can run

sudo snap revert telegram-desktop

else

sudo snap refresh telegram-desktop --revision  6597

giox069 · 2025-05-20T06:58:30Z

Same issue here on three different installation of Kubuntu 25.04, KDE, Wayland, Intel CPU/GPU (i5 5th, 7th an 10th gen)

raf092 · 2025-05-20T18:21:14Z

Same here, Kubuntu 25.04 after snap update Telegram stopped working. AMD GPU and CPU. After downgrading the app it started working again, just type: sudo snap refresh telegram-desktop --revision 6597

fenris · 2025-05-21T06:47:42Z

The downgrading method is just temporary ... when the snap refresh, it upgrades to the latest stable, and it breaks again. Any update on this issue is much appreciated.

Currently, running using the upstream Linux binary.

ilya-fedin · 2025-05-21T08:06:13Z

Nothing new sadly, I have only VMs with LTS flavours of Ubuntu and none of them reproduced this issue (the only one supporting Wayland of them is the GNOME flavour, though). The only things I can suggest is to either stick to LTS versions or use the non-snap versions.

People liking to experiment could try to reinstall the snap with --devmode that disables sandbox, as the error says "Qt is unable to allocate memory for graphics buffer" and sandbox could be the cause.

soumyaDghosh · 2025-05-21T09:39:44Z

I just ran it in KDE Neon, the issue is same in Wayland.

The downgrading method is just temporary ... when the snap refresh, it upgrades to the latest stable, and it breaks again. Any update on this issue is much appreciated.

You can hold the update using

sudo snap refresh --hold=forever telegram-desktop

To remove the hold,

sudo snap refresh --unhold telegram-desktop

compulov · 2025-05-21T10:28:10Z

Running into the same issue with the current snap on Kubuntu 25.04, Framework Ryzen AI. For what it's worth, the binary release works fine.
Has anyone tried X11 vs Wayland? Just wondering given the number of Wayland errors, but I assume they might have been caused by the preceding Qt errors.
One more edit... The Flatpak works fine, too. 5.4.13.

benoitg · 2025-05-21T11:03:03Z

Indeed, installing with --devmode telegram works fine.

I have the same error on Kubuntu 25.04 after last update.
It works for me. Thank you!

@marcusboden both outputs look identical to me, only that the first one is longer due to apparently the app being run for a longer time. I don't see anything related, it seem to mention only dbus calls and real time priority, nothing related to mmap.

AtFreezingPoint · 2025-05-23T19:15:49Z

Same problem 👍🏽

kenvandine · 2025-05-24T12:06:48Z

Does it work by forcing it to fallback to Xwayland?

DISABLE_WAYLAND=1 telegram-desktop

AtFreezingPoint · 2025-05-24T14:17:18Z

Does it work by forcing it to fallback to Xwayland?

DISABLE_WAYLAND=1 telegram-desktop

Checked, yes.

Also works with these steps

1. snap run --shell telegram-desktop

2. export QT_QPA_PLATFORM=xcb

3. telegram-desktop

AtFreezingPoint · 2025-05-24T17:52:14Z

DISABLE_WAYLAND=1 telegram-desktop

Believe it or not that exact same command started not working on my system... Wow

AtFreezingPoint · 2025-05-24T19:39:50Z

Edge build also suffering from issue.

adeptg · 2025-05-24T20:04:25Z

"DISABLE_WAYLAND=1 telegram-desktop" worked for me 2 times. Successful run:

then I tried to run telegram-desktop without this option, and it failed (as was expected).

But now DISABLE_WAYLAND=1 doesn't help anymore:
