Is this a regression or has this always been like this for you? I wonder if this is related to https://phabricator.kde.org/T15916 .

Tested Dolphin 23.08.4 on a live usb of neon stable edition, the context menu takes 1 second to open.
On Arch Linux running Dolphin 24.01.95-1 the delay is 3 seconds. Tested with the same files on both systems.

Interesting. I am not aware of any relevant changes happening to Dolphin code or context menu triggering since 23.08, so this might be a Qt6 or KF6 regression. It probably needs profiling either way though to pinpoint what is taking so long.
