Mixer > Main EQ > Graphic Equalizer isn't usable

[idcmp]

Bug Description

Apologies if this is fixed in a newer version.

1. the yellow you see is the text from my crates in the main Mixxx window, somehow shining through the Preferences window.
2. clicking on the circle in the slider will cause the EQ amount to jump wildly.
3. clicking on a slider will cause other sliders to shift slightly (but the values stay the same).

The values change too violently to use this live to make adjustments. I can take a video snapshot if that helps.

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.

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.

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.
