Drag/scrolling impossible on Wayland

[morgannunan]

Bug Description

If I'm running Xorg, dragging my tracks around my playlists works as expected; however, if I'm running Wayland, I can't drag a track up above the scoll line. It simply won't initiate scrolling to drag the file up. Also, if I try to drag a file down from my deck into a position in my playlist, as soon as the track crosses over the playlist, the whole panel starts scrolling itself up automatically.

Version

2.4.2

OS

Ubuntu 24.04

Hmm, this is a bit like #14038. I'm afraid there's not much Mixxx can do about it.

Mixxx doesn't handle the auto-scroll itself, it uses the functions of QTableView / QAbstractItemView.

Do you mind trying Mixxx 2.5? https://mixxx.org/download/#beta
(still marked beta, but already on the doorstep, ready to be released next week)
IIRC Mixxx does still not guarantee down-grading (even though no issues were reported lately), so please make a backup just in case you decide to go back to 2.4.2

It is like that other issue. I upgraded to 2.5 and I got the same problem: now it only scrolls up one line.

I'm looking through the controls now, and assigning hotkeys. Alt + arrow keys will move whatever's selected up and down through the playlists, which, honestly, is a better solution anyway.

edit// except I just realized these alt + arrow keys don't work in wayland.

Another issue in Wayland is that hold and drag is not holding, half the time. I'll click and hold, then drag, and the item won't come with me. I'll click it again and drag and often times it'll just release halfway to its destination.

These seem like they're more likely Wayland / QT problems than Mixxx ones, but I'm not sure. I can move my comments over to Wayland or QT, whatever you think is more appropriate.

I can confirm "an" issue with Ubuntu 24.04. I can move a track on the top visible row and it scrolls one line. When I move the mouse a bit it scrolls more lines. On Ubuntu 22.04 there is not such an issue. It keeps scrolling when holding the mouse in this position with no moving. This has been tested with the resent 2.5 branch.

Can you please file new issues for you other findings? We can only track one bug per issue.
