Comment 1 Bug Janitor Service 2022-08-18 19:29:30 UTC 
A possibly relevant merge request was started @ https://invent.kde.org/multimedia/elisa/-/merge_requests/381
Comment 2 Nate Graham 2022-08-18 20:01:00 UTC 
Seems to have been fixed at some point, as I can't reproduce this in current git master, but I could in the past.
Comment 3 Yerrey Dev 2022-08-19 01:27:24 UTC 
Can still reproduce on git master.
Comment 4 Jack Hill 2022-08-19 10:25:28 UTC 
Using 22.04.2, I also can't reproduce it any more. I switched to Fedora a few days ago, so maybe the bug isn't present on Fedora (36).

Yes, most likely, the bug disappeared due to the transition to Fedora. On Archlinux, the problem is still relevant
Comment 6 Nate Graham 2022-08-19 19:20:18 UTC 
I'm on Fedora too, but I build Elisa from source and I can't reproduce it.
Comment 7 Yerrey Dev 2022-08-19 20:21:30 UTC 
If I had to guess, could it be libvlc issue? Those who can't reproduce, what libvlc version are you running? KDE Unstable Neon is at 3.0.9.2-1 at the moment.
Comment 8 Jack Hill 2022-08-22 17:44:44 UTC 
Problem also doesn't exist on openSUSE Tumbleweed 20220821.

Fedora doesn't have libvlc installed by default, and I manually uninstalled vlc on tumbleweed.

Fedora and Tumbleweed both use Qt 5.15.5 now. Maybe it was a bug in Qt Multimedia that was fixed in 5.15.5? Does arch still use 5.15.2?
Comment 9 Dmitry 2022-08-23 07:30:38 UTC 
(In reply to Jack Hill from comment #8)

No, I definitely use 5.15.5 on Archlinux

Emit positionChanged when seeking with vlc backend

It seems that vlc does not generate an event when calling libvlc_media_player_set_position,
so we have to do it ourselves
