Interesting, I'm doing the same but it works fine... Perhaps Qt's clipboard implementation is still incompatible with GNOME and someone should report to them. Would you like to do that?

[lapisdecor]

Looks like it's a Wayland problem. I switched to Xorg and it works fine.

[ilya-fedin]

Well, tdesktop doesn't differ between Wayland and Xorg, it just creates QTextEdit that handles all the input field and Qt does all the underlying work.

[Aokromes]

works for me also on default ubuntu 23.04 without install.

[Aokromes]

and installing i don't have problem too.

[lapisdecor]

Could you try to paste more than one time?

[Aokromes]

tried like 5 different urls without problem.

[ilya-fedin]

Works just fine for me, too

[lapisdecor]

This is strange. It happens here at leat on two computers with ubuntu 23.04 on wayland.

Maybe there are steps to reproduce you're missing? Try to reproduce on a clean VM installation to replicate the @Aokromes's environment and learn what else he should do to reproduce.

[lapisdecor]

I tried on a clean VM and can't reproduce. I also tried creating a new user on this machine and the bug happens for the new user with a fresh Telegram install.

[ilya-fedin]

Apparently there's something special to your installations?

[lapisdecor]

On another computer with Ubuntu 22.04 with another Telegram user, on Wayland, I first couldn't reproduce, but after a short while, it happend too.

[ilya-fedin]

Well, we need a way to report this to Qt... I don't imagine how to fix such kind of bug on tdesktop level.

[lapisdecor]

By the way, it only happened after I switched the user I sent the message to. Could this be something in my network? (I'm getting paranoid here)

[ilya-fedin]

I would rather guess it's something to focus change in GNOME and graphics drivers. Reports from GNOME users related to focus change are frequent so it feels like this part of GNOME is constantly broken. Maybe they even achieved to make such bugs dependent on OpenGL drivers or something. They test gtk applications and they usually have no problems, but for Qt applications GNOME has new weird bugs in each new release.

[lapisdecor]

After I paste, the paste option disappears on Telegram, but I can paste in LibreOffice.

[ilya-fedin]

So?

[ilya-fedin]

I don't understand how that's relevant. I'm not surprised gtk applications work fine.

[lapisdecor]

Well shouldn't the text on memory be available after a paste? So you could paste a second time...

[ilya-fedin]

How would you access it if Qt thinks it's not present?

[lapisdecor]

Oh, I see...

[ilya-fedin]

I tend to think it's likely due to #26407. The bug is worked around to filter the event closing the popup but Qt still thinks application loses focus and likely other side effects happen like clearing the clipboard.

[Psychosynthesis]

Got the same problem on Ubuntu, but not only with Firefox.

Bug with paste from buffer does not occur every time, it is a "floating" bug. It’s just that sometimes pasting using one of the methods does not work, alternating helps, for example, through the right mouse button menu, pasting does not occur, but if you select the desired text and copy it via “ctrl+c”, pasting works.

In my opinion, the problem is most likely in the implementation of the buffer on Ubuntu, however, in Windows 7 I received a similar problem several times. It is difficult to trace the cause.

[ilya-fedin]

There's a build using Qt 6.6 (that has a proper fix for #26407) on snap edge channel, you can try it to check whether it helps with this.

[lapisdecor]

Thanks, I'll check it out.

With the edge snap I get a segmentation fault after configuring the user: telegram-desktop [ALSOFT] (EE) Failed to connect PipeWire event context (errno: 112) propsReply "An AppArmor policy prevents this sender from sending this message to this recipient; type=\"method_call\", sender=\":1.157\" (uid=1000 pid=10455 comm=\"/snap/telegram-desktop/5101/usr/bin/telegram-deskt\" label=\"snap.telegram-desktop.telegram-desktop (enforce)\") interface=\"org.freedesktop.DBus.Properties\" member=\"GetAll\" error name=\"(unset)\" requested_reply=\"0\" destination=\"org.freedesktop.NetworkManager\" (uid=0 pid=1336 comm=\"/usr/sbin/NetworkManager --no-daemon\" label=\"unconfined\")" QPainter::begin: Paint device returned engine == 0, type: 2 QWidget::render: Cannot render with an inactive painter qt.svg: Error while inflating gzip file: SVG format check failed Falta de segmentação (núcleo despejado)

[lapisdecor]

Version 4.10.1 which is in the stable channel seems to work, so far... the bug didn't reproduce yet.

[ilya-fedin]

Yeah, it seems Qt 6.6 has some bug in qtsvg. Snap should have a workaround soon by excluding the QImage qtsvg plugin.

[ilya-fedin]

Snap edge should work now

[ilya-fedin]

Does this happen with 4.10.2?

[lapisdecor]

Not yet. Maybe it's solved.

Could the issue be closed?

Yes. All seems fine now.
