Waveform Display Freezes Randomly

[martinprad0]

Bug Description

My experience with the 2.6 beta version has been flawless for the last 4 weeks. However, today I started experiencing constant freezes on the Waveform display (the rest of the interface is working) that I don't seem to find the cause. I think it must be something related to OpenGL and VSync but I'm not really sure. I can fix the issue by changing the focus on another window or pressing Alt, but it's really annoying.

Here's a video of the event occurring randomly
https://youtu.be/-G4M264wFQw

I launched the program on the terminal and found nothing on the verbose. For more information, here's my OS information

Seems that turning acceleration off in Waveform Settings fixes the issue. I tried to replicate this issue on the dnf last release version 2.5. and this seems to be a problem only related to version 2.6. However, even when I turn off the acceleration, there seems to be a lot of frame drops.

Edit: I want to use this first comment to update on some things I might discover on the way. The first I noticed is that every time a frame drop occurs, the debug terminal shows:

debug [Main] Processing QEvent::MetaCall for object WaveformWidgetFactory(0x1d476010) running in thread: "Main" took 130 ms

Edit 2: I activated acceleration again to test what's causing the freeze. Exactly at the moment of the freeze I got the following message:

debug [Main] Processing QEvent::MetaCall for object WaveformwWidgetFactory(0x3d6963a0) running in thread: "Main" took 134 ms

Edit 3: I just unfreezed (by Pressing ALT to display menu bar) it and while I was doing it I got the following debug message:

I don't really know if these messages got something to do. However, the tracks listed in the message are some of the tracks that were at my sight in the library the moment everything happened:

Is this caused by an mixxx update? Do you build Mixxx from source? Can you remember if there is a Mixxx version in the 2.6 branch that works good?

I built from source. This is the version the About window gave me:

Git Version: 2.6-beta-17-gfc2b718820
Qt Version: 6.8.3

I've been using this same version for the last 4 weeks. But I've also made some system upgrades and those may have broken something. I will be testing this exact same version on another laptop so I can be providing your team more information.

These are probably signals for the DDJ's VU meter

Yes, I am aware 😅

Does the waveform unfreeze after you maximize and then unmaximize the library?
