Works for me. Any chance you can attach a screen recording that shows the issue? Thanks!

Screen recording showing menu pop-up

The screen recording is attached.  It happens only if I hold the mouse still for a fraction of a second after clicking on the slider, it's OK if I move the mouse immediately.

Thanks, that's very helpful. Can reproduce.

This preview UI comes from baloo-widgets; moving there.
Comment 4 Stefan Brüns 2021-01-08 19:21:36 UTC 
Thats the right mouse button emulation triggered by a long click, it shows the context menu (See Qt::TapAndHoldGesture, https://doc.qt.io/qt-5/gestures-overview.html).

This is explicitly enabled by dolphin (panels/information/informationpanelcontent.cpp).
Comment 5 Nate Graham 2021-01-08 19:22:36 UTC 
Aha! Thanks for the investigation.

Would this be to give access to the right mouse button menu on touch screens, and if so could dolphin enable it only on touch screen devices?

It does make dragging the slider very difficult on my desktop PC.

Can reproduce with Dolphin 21.04.1 on Arch Linux.
Comment 8 Marco Antonucci 2025-02-25 04:31:53 UTC 
Same with Dolphin 23.08.5 on Kubuntu 24.04. This makes using the slider seeking specific moments in long recordings (for example, meetings recordings) really difficult.
