Items missing from the system tray icon right click menu

[sha-265]

qBittorrent & operating system versions

qBittorrent: 4.5.0 x64
Operating system: Ubuntu 22.10
Qt: 5.15.6
libtorrent-rasterbar: 2.0.8.0

What is the problem?

In the right click menu of the system tray icon in the notification area, all the items are missing except the Exit button, like this:

Steps to reproduce

1. Run qBittorrent 4.5.0.
2. Try to right click on the tray icon.
3. See if all buttons appears or only Exit button.

Additional context

The menu should be like this:

Possible workaround: disable the Show qBittorrent in notification area option and than re-enable it. For me all items appears, until next restart of the app.

Out of curiosity can you also test with official AppImage (download on mainstite)?

@sledgehammer999, with the AppImage file the right click menu doesn't work at all.

[sha-265]

The system tray icon right click menu is not working also in qBittorrent v4.5.0 installed from PPA on Ubuntu 22.04.

[sledgehammer999]

Which DE are you using?
I have tried clean VMs of Ubuntu 22.10 (gnome), Xubuntu 22.10 (xfce) and Arch (KDE).
I can't reproduce it. The tray menu works correctly with the PPA version and the AppImage on the above VMs.

Were you using another qbt version before on the same OS? Did it work correctly?

[sha-265]

Which DE are you using?

Both versions (22.04 and 22.10) use Ubuntu's default DE - aka gnome.

Were you using another qbt version before on the same OS? Did it work correctly?

I did. I used v4.4.5 (and older) on the same OS, and it did work correctly.

Is anyone able to do their own compilations? If so, can you try with this patch? patch->#18108

I don't think this patch can fix this issue. I'm thinking on possible solution... Of course it would be nice if someone affected could test it when I'm done.

[Rootdiv]

I have the same problem.

In the update dated December 4, 2022, the problem persists.

qBittorrent: 4.5.0 x64
Operating system: Ubuntu Mate 22.04.1
DE: Mate 1.26.0
Qt: 5.15.3
libtorrent-rasterbar: 2.0.8.0
echo $QT_QPA_PLATFORMTHEME -> gtk2

[glassez]

It looks like there is incompatibility with some DE (tray icon providers used by them). I'll try to find a workaround as soon as I get a similar environment.

[glassez]

Which DE are you using?
I have tried clean VMs of Ubuntu 22.10 (gnome), Xubuntu 22.10 (xfce) and Arch (KDE).
I can't reproduce it. 

I can't reproduce it on Linux Mint (neither on Cinnamon, nor on Xfce, nor on Mate).

What does the following return?

echo $QT_QPA_PLATFORMTHEME

What does it return for you on mentioned above desktops?

@glassez, I'm edited comment #18074 (comment)

This issue is reproducible when starting is slow. I successfully reproduced the problem in a clean VM using Arch Linux + MATE after adding a torrent with 43000 small files.

The version of Qt does not matter. I tried to recompile qBittorrent with Qt5 and Qt6 — the behavior is slightly different, but both are broken.

[glassez]

I'm not very familiar with Linux world, but apparently there are different backends providing the tray icon functionality, and the problem is with some of them, regardless of the DE itself.

This issue is reproducible when starting is slow. I successfully reproduced the problem in a clean VM using Arch Linux + MATE after adding a torrent with 43000 small files.

Didn't test with real torrent but I added extra delay of 10 secs to emulate it. First the reduced menu is shown while torrents are being loaded (delay isn't expired) and then it is replaced with full menu as expected.

[andreymal]

@glassez it's not replaced in my clean VM

[mtigas]

Same behavior here (missing tray menu items). Have not noticed any particular slowness or any change in behavior after some time; the menu items simply do not appear. This was an upgrade of an existing install, and so I do have several torrents in the app already.

Workaround in original post (Behavior -> "Show qBittorrent in notification area", toggle off, click "Apply", toggle it on, click "Apply") seems to work and causes the menu items to appear properly until the app is restarted.

I made a VM but I wasn't able to make the same problem happen.

I got rid of the Status Tray Plugin and then re-added it to my panel and now I see all of the menu options but when I quit qbit and re launch it I get the same problem as before. I have also unchecked Show qBittorrent minimized in the Behavior Preferences and when I recheck it I see the all of the menu options but when I quit qbit it goes back to the same problem.

I might reinstall qbittorrent later today to see if that fixes it but I'm not sure since I haven't been able to find a way to replicate my problem tell me what I should do. I don't mind keeping this bug until we get it fixed?

[andreymal]

I made a VM but I wasn't able to make the same problem happen.

@MrComexs try to add some torrents, preferably with a large number of files (as I mentioned before)

[glassez]

Well, I seem to have noticed some regularity that I was able to reproduce on two different Linux systems:

1. if there are no torrents in qBittorrent, then tray menu always works correctly.
2. if there are any torrents (one was enough for me), then tray menu works correctly when qBittorrent is first started after the OS is loaded, but it does not work correctly on every next restart of qBittorrent until the OS is rebooted (or until you delete all torrents).

Can anyone confirm this behavior?

[andreymal]

@glassez in my PC and clean VM, the menu does not work correctly even on first start. I guess my torrents are "big enough" to consistently trigger some race condition

[glassez]

@andreymal
How does it work on your system if you don't have a single torrent?

[andreymal]

@glassez running a separate instance with a empty home directory works well

qbittorrent-empty-home.mp4

[glassez]

@andreymal
Could you also test it with single not so big torrent? Does it works correctly once after OS restart?
Could you provide your "big" torrent to me for testing or it is private?

[andreymal]

@glassez I tried to use this simple Python script to generate many small files:

from pathlib import Path
d = Path("many-files")
d.mkdir(exist_ok=True)
for num in range(10000):
    (d / f"{num}.txt").write_text(f"File #{num}\n", "utf-8")

Then I just created and added a torrent in qBittorrent (no need to download it, you can even delete the original files).

The more files created, the greater the chance of triggering this bug.

10000 files are enough for me to trigger this bug, but note that I'm using an HDD (I guess the behavior may be different on SSD)

(I also tried to create a torrent with 500000 files, but it failed with bencoded item count limit exceeded lol)

Can anyone confirm this behavior?

@glassez

1. Yes
2. With only 1 torrent in the BT_backup folder (32~GiB but only 4 files downloaded 1 half downloaded and 3 not downloaded) I would never get the bug to occur
3. it took me 30~ torrents in the BT_backup folder for the bug to occur then when I rebooted it amount of torrent need for the bug to occur was bumped up to 35~. Then when I rebooted it work just fine until I killed it and relaunched it then the bug occur. If I rebooted it for the third or more times I don't get the bug until I killed it and relaunch it.
4. I re-add all my torrents back into the BT_backup folder all 67 of them then no matter how many times I reboot, I only see the exit menu option.
   (number 3 and 4 are both number 2)

Note: I moved the .torrent and .fastresume file out of the BT_backup and add 5 torrents at a time until I got the bug to occur. I still left the downloaded files in there respective categories folder but only moved the .torrent and .fastresume files out of the BT_backup folder so I don't have to re-download the torrents content.

[glassez]

Well, after agonizing attempts to figure out what's what, I came to understand that the problem is hidden somewhere in the depths of Qt (platform plugin), so I won't be able to achieve a "clean" solution to this problem.
All I can do is completely reload the system tray icon if necessary to replace the menu (i.e. after all torrents are restored). Now #18250 implements that. The disadvantage is the visual effect (the icon disappears, and then reappears).
Another way would be to have no menu at all until the torrents are restored so I can show regular menu.
So I'm waiting for your feedback. It would also be very helpful if you could test it yourself to confirm that it behaves as intended on your platforms as well.

P.S. I explain for those who have not understood this so far that since version 4.5, the application startup (restoring existing torrents) process has been significantly optimized, one of the aspects of which is that the main UI (including the regular tray icon menu) becomes available only at the end of the startup, and during the startup there is only minimal UI functionality displaying the current progress and allowing you to interrupt it, i.e. close the application.

[MrComexs]

I was able to get the menu to (kinda) work again for me but all I did was give qBittorrent more ram.
so by default Physical memory (RAM) usage limit (?) = 512 I set it to Physical memory (RAM) usage limit (?) = 1024 without restarting qBittorrent the menu is working as it should.

[glassez]

I set it to Physical memory (RAM) usage limit (?) = 1024 without restarting qBittorrent the menu is working as it should.

I wonder how it will behave after restarting qBittorrent?
