CopyQ changes cursor to rotating circle under Ubuntu 26.04 when clipboard item is selected

[CRogersMedia]

Describe the bug
When selecting an item that was previously copied from the copyQ dropdown in the GNOME extension tray icon, the cursor turns to a rotating circle (usually indicating the system is busy doing something). This eventually goes away, after a prolonged time (10-40 seconds) after mousing over things on another application.

To Reproduce

1. Run CopyQ on Ubuntu 26.04
2. Copy a few things to clipboard (regular text)
3. Click the copyQ extension indicator on top GNOME bar, and select a previously copied text entry.

Expected behavior
Item should be copied to clipboard without any change in cursor state.

It could be a problem with the extension. Does this happen if you select the item from the menu opened via copyq menu command?

It is a bug in Ubuntu: ubuntu/gnome-shell-extension-appindicator#443

I've added StartupNotify=false to the com.github.hluk.copyq.desktop file. Unfortunately, it may not help in this case due to the bug in the GNOME extension. There is a new entry to document this in Known Issues: https://copyq.readthedocs.io/en/latest/known-issues.html#on-gnome-busy-cursor-after-selecting-tray-menu-item
