[SheriBlonde]

Mixxx used to work until I upgraded to mixx 2.3.4

Mixxx hangs when I start it.

When I run .\mixxx.exe --safe-mode

C:\Program Files\Mixxx>.\mixxx.exe --safe-mode

C:\Program Files\Mixxx>AsioDrv::: CAsioDrv()…

AMD drivers 23.2.1 and 23.2.2 give the same errors.

We have some (152) intermediate builds between 2.3.3 and 2.3.4 here: https://downloads.mixxx.org/snapshots/2.3
It would very helpful to find the first one that introduces the issue.

This is a candidate: a0ffb6b

Can you try out:
https://downloads.mixxx.org/snapshots/2.3/mixxx-2.3.3-52-gaf27d63157-win64.msi
https://downloads.mixxx.org/snapshots/2.3/mixxx-2.3.3-53-ga0ffb6b0a8-win64.msi

From there we may crawl up or down by halving the distance to the last known good or bad build.

2.3.3-52 works
2.3.3-53 Hangs

[SheriBlonde]

What changed between 22.3.3-52 and 2.3.3-53 that would make it stop working?
I am going to use 22.3.3-52 for now.
I'm also trying to map a Pioneer DDJ-FLX4 to mixxx.

I tried looking up stuff on sglShareLists() failed and I don't think I understand what they are talking about.

works!

Hangs in the starting slash screen!

I have 32 Gigs of memory ...

The error I get is wglShareLists() failed.

2.3.3-53 has the flag "--disableVuMeterGL" that aims to revert the change. Does it fix the issue?

[daschuer]

The error message is created here:
https://github.com/qt/qtbase/blob/4ee4fc18b4067b90efa46ca9baba74f53b54d9ec/src/plugins/platforms/windows/qwindowsglcontext.cpp#L491

from the windows error code ERROR_MOD_NOT_FOUND.

2.3.3-53 has the flag "--disableVuMeterGL" that aims to revert the change. Does it fix the issue?

Yes --disableVuMeterGL
causes mixxx to load!!! Yaya!!
What is happening here?

[daschuer]

I have just noticed that the "--safe-mode" parameter has been introduced with Mixxx 2.4-alpha. In Mixxx 2.3.4 only "--safeMode" is available. Can you check if Mixxx starts with .\mixxx.exe --safeMode. My guess is yes.

To fix this bug, we may either set --disableVuMeterGL automatically or find the root cause of the issue.
Can you please attache a complete mixxx.log form a run with and without --disableVuMeterGL ? Hopefully it will reveal some hints we can use for the fix.

[m0dB]

We could at least disable VuMeterGL on Windows by default until we figure this out. We have not had similar reports of problems on macOS or Linux, right?

[m0dB]

@SheriBlonde in your Preferences dialog, Waveforms tab, do you have the "RGB (GLSL)" waveform listed in the waveform type popup menu? Does it work?

[daschuer]

We have not had similar reports of problems on macOS or Linux, right?

Right, but we have also no one that is confirming this bug. If we good a confirmation, that would rectify a quick fix release for me.

[SheriBlonde]

I don't understand what's going on,
I uninstalled 2.3.3 and installed, 2.3.4 (HEAD) works now.
Maybe it's related to plugging in the DDJ-FLX4 controller?
Not sure what's going on....

[SheriBlonde]

// I mean I uninstalled 2.3.3 and installed 2.3.4 ...

[m0dB]

I doubt it is related to plugging in the controller. Please let me know if you run into the issue again.

In the mean time, it would be great if you could give the build from my gopengl_renderers branch a try. You can find a windows installer at the bottom of this page:

https://github.com/mixxxdj/mixxx/actions/runs/4337377093

Ideally selecting the RGB (QOpenGL) (GLSL) waveform type.

[SheriBlonde]

Plugged in the controller, it works.
One thing I notice is that the line under where it says mixxx on the starting/splash screen is coloured, it used to be gray.

[SheriBlonde]

Installed

https://github.com/mixxxdj/mixxx/actions/runs/4337377093

[SheriBlonde]

How do I "Ideally selecting the RGB (QOpenGL) (GLSL) waveform type."

[m0dB]

In the preferences dialog (maybe called settings on windows?), waveforms, waveform type drop down. You will not have this RGB (QOpenGL) (GLSL) option with 2.3.4, but it should appear if you installed this version.

[daschuer]

@SheriBlonde I can imagine your issue was related to a missing DLL so that it has ben fixed by the new installation.
Can you confirm that you are now able to run Mixxx from the start menu without any command line flags?

Can you than try to rename the libEGL.dll or the libGLESv2.dll in C:\program files\mixxx and try if you are able to reproduce the issue?

Expired for Mixxx because there has been no activity for 60 days.
