Mixxx 2.2 slows down by graphical error

[Jose]

I have updated to Mixxx 2.2. in Mageia 6.1 and it gives me graphic error in the music list.
Attach error link as demonstration.

I have tried to disable the graphic effects of Plasma 5 and it still works badly. I had to go back to version 2.1.5

It looks like something strange is going on with the preview column in the library. Is it okay if you hide that? Right click the header row of the library table to select which columns to show.

[Jose (joselpdj)]

I removed the preview from the library and the problem keeps playing.

What GPU and graphics driver do you use? Do you use X11 or Wayland? Can you reproduce this with different options for waveform renderer in Preferences -> Waveforms?

[Jose (joselpdj)]

I have tested with all wave types and still giving the same error. Attached screen captiras of the graphic configuration of the computer where I have installed Mixxx.

I have the same problem with archlinux and kde plasma. Mixxx on i3 works without a problem. This only occures with the qt5 stuff, mixxx 2.1 (maybe 2.2) with qt4 worked without problems.
My system is a thinkpad t540p with an intel gpu. Using modesetting or intel drivers doesn't change a thing. Might be related to some kde/plasma stuff? Disabling composer also didn't help.

Just added some tracks on kde to a crate (kde is my main de, i'm using i3 only for djing ^^) and saw that there are some errors in the log which i don't have on i3:

I currently can't reproduce this anymore, neither with mixxx 2.2.1 nor with mixxx 2.3 (from latest git master). As it seems like this bug only happend on kde/plasma, maybe it was a bug on their side?

I'm using:
plasma-desktop 5.15.5-1
plasma-framework 5.58.0-1
qt5-base 5.12.3-2

[Jose (joselpdj)]

It seems that with version 2.2.1 this error no longer occurs. It can be taken for granted as of version 2.2.1.

Regards!!

[Jose (joselpdj)]

I'm using

Mageia 7 Rc
Plasma-desktop: 5.15.4
Plasma-framework: 5.57
Qt version: 5.12.2

Thank you for confirmation.
