Mixer > Main EQ > Graphic Equalizer isn't usable

At least the opacity issue should have been fixed by #11647
Can you confirm the waveforms framerate slider and the end-of-track slider work as desired?
If yes, it may be that the fix from #11647 only applies to existing sliders (instantiated by the .ui files).
In contrast, the main EQ sliders are added on demand, when the effect settings are restored and when the main EQ effect is changed.
So maybe an update() or style()->polish() call solves the issue.

The other issues are new.

Potential fix is #12631, please test!

Is this a regression compared to 2.3.6?

[daschuer]

It is a regression compared to 2.3.6 and 2.5-alpha
Since we have no idea how to solve it, I have removed the experimental PRs from the 2.4 milestone. It will be fixed with the 2.5 release.

Seems to be a Qt 5 bug, I've added some notes here: #12711 (comment)

@daschuer Running 1c6b44c (gh12630) (off of your fork), I still experience this problem.

[fwcd]

That looks like a 2.4 build, which presumably still has the buggy Qt 5 version. We'll either have to patch Qt or you could try the 2.5 snapshots, which run Qt 6 and shouldn't have the issue.

Grabbed 2.5-alpha-250-gd21cb08ce3 (main)

Can confirm the Graphic Equalizer has gone from broken to just frustrating. (Which is an improvement!)

The knob is quite large, and it's almost impossible to click on the knob without causing the value to change, and it's not obvious how it will change when I click.

Infact, because the movement of the knob isn't 1:1 with the movement of my pointer on the screen, it's possible to click-and-drag, but then let go - and without moving my mouse - click again and cause the EQ knob to move.

Can you check out:
#12711

Does it make any difference? Are you able to build from source and merge this to the main branch? I am curious if this removes the "frustration" as well.

Unfortunately I don't have a dev toolchain installed on this Mac, and that's not an undertaking I have time for right now. If there's a PR-build I can download, I don't mind giving it a try though.

I will probably do it eventually as I need to remove "Add to AutoDJ (replace)" from the popup menu. 😭

Can you file an issue for this? We may make it conditional via preferences or add a "really?" pop up.

Please test the Qt6 build you will find here: https://github.com/mixxxdj/mixxx/actions/runs/8001196736?pr=12862
