Hi Leo,

The issue appears to be a segmentation fault caused by the premature deletion of an object, likely within the Qt6 event handling system. Jonas is correct that the backtrace doesn't clearly indicate the exact problem, and we need to take some steps to diagnose and potentially resolve the issue:

Gather More Information
Crash Timing: Does the crash occur during specific actions (e.g., changing songs, idle state, playlist interactions)?
Playback Context: Are there any specific file types or codecs involved when the crash happens?
Reproducibility: Can you reliably reproduce the crash? If yes, describe the steps.

System and Package Details
You mentioned you are using the Liquorix kernel. Did you install Strawberry from a package (e.g., a Debian/Ubuntu .deb) or build it from source? If from a package, specify its source.

Check for library mismatches:

Run

ldd $(which strawberry)

(to see if any library paths point to unexpected or mismatched versions)

Check Dependencies
Ensure that all the required dependencies, particularly libQt6Core and libQt6Widgets, are consistent with the Strawberry version. Use: dpkg -l | grep qt6

(to ensure they match the versions expected by Strawberry 1.2.2)

Workaround Suggestions

Switch to a Stable Kernel: Since you're on Liquorix, consider trying the default kernel of your distribution to rule out kernel-specific issues.
Downgrade Strawberry: Temporarily revert to the previous version if stability is critical while investigating further:

sudo apt install strawberry=1.2.1

@jonas You cry for no contributions but then you make a year/monthly suscription. WTF? Put a mandatory single payment, man!!

@Sharky-PI, I remove the second comment field if it is causing a problem.

@jonas I would not say that I completely gave up, but I just started a new position in a company so I lost that whole free time to mess with this particular thing

I went making https://github.com/guprobr/WakkaQt instead to learn a bit more Qt before resuming this task
The last ideas we discussed, I never tried... but the last post on projectM made me feel second toughts on the viability of the idea.... anyway, i want to resume this task someday I don't think we should give up but certainly something is missing in the backend inner parts of how Qt works with OpenGL and how projectM works with OpenGL, as it was discussed on the thread on github.

But the first thing i would do is trying with latest Qt LTS, before anything.
Second thing, to try with the same version on Windows!
We have to figure where the problem is. Obviously its a Qt issue, but what made me stop working on it was when SDL window version showed the same issues. That was very disappointing.

PS: sorry to take so long to answer, I just saw this today
