Description Alexander Reinholdt 2021-09-24 06:54:53 UTC

SUMMARY

When hovering over a submenu of KStatusNotifierItem's context menu the first time, very often the submenu is opened to the wrong side.

A user of Smb4K made a video showing this bug very nicely (see also bug report 442187): https://imgur.com/a/WGs2NP9

Besides Smb4K at least also Yakuake is affected by this bug (Height and Width submenus).  


STEPS TO REPRODUCE
1. Open the context menu of the status notifier item.
2. Hover over a submenu the first time.

OBSERVED RESULT

The submenu opens to the wrong side and, hence, cannot be seen and used. After moving away and hovering back over the submenu, it most of the time opens to the correct side.

EXPECTED RESULT

The submenu always opens to the correct side.

Test case: Simple AppIndicator3 in Python

Can confirm AppIndicator3 (GTK) and Ayatana Indicator tray icons are affected too. Both in single monitor and multiple monitor setups.

Attached is a simple test case to replicate this with a simple Python application. If necessary, replace "AppIndicator3" with "AyatanaAppIndicator3" depending on the Python implementation available for your distro (both APIs are compatible). I was writing this for a new bug report until I found this one, originally suspecting it was a GTK integration bug.

Comment 2 Jens Gwerder 2023-05-17 18:52:31 UTC

I can confirm this issue too, which I noticed with polychromatic.
I'm using Ayatana Indicator (v0.9.3-1).

Comment 3 Hamish Robertson 2024-03-26 09:38:49 UTC

This is still an issue in KStatusNotifierItem 6.0.0.

Comment 4 Hamish Robertson 2025-01-10 09:43:12 UTC

I believe this was fixed in Plasma 6.2 in October 2024.

Comment 5 Luke Horwell 2025-01-10 12:13:48 UTC

The bug is still present in Plasma 6.2.5. Using the Python test case (attachment), I can still reproduce the issue as described (menus open _initially_ to the wrong side).

Tested under:
Arch Linux
KDE Plasma 6.2.5
KDE Frameworks 6.9.0
Qt Version 6.8.1
X11

Does the test case work for you? If the issue was indeed fixed, please could you share details of your environment and the app? Additionally, if there were specific commits or changes that addressed this bug, I’d appreciate a reference to help verify - I couldn't see any specific commits.

Test case: QSystemTrayIcon in Python (PyQt6)

Here's another test case to demonstrate, using QSystemTrayIcon (Qt) via PyQt6.

Comment 7 Hamish Robertson 2025-01-16 09:40:36 UTC

Your PyQt6 works correctly for me.
I guess the difference is Wayland which I probably switched to at the same time as updating to Plasma 6.2.

Tested under:
Arch Linux 
KDE Plasma Version: 6.2.5
KDE Frameworks Version: 6.10.0
Qt Version: 6.8.1
Kernel Version: 6.12.9-arch1-1 (64-bit)
Graphics Platform: Wayland

Comment 8 Marco Martin 2025-01-16 15:07:02 UTC

is the issue of the menu actually opening off-screen?
