Milkdrop Visualizer not working

[Grassgrowz]

Desktop

• OS: Linux Mint, kernel 5.15.0-171-generic
• OS version: 21.3
• Tauon Version: 9.0.0
• Installation method: Flatpak from Software Manager

Describe the bug
When activating the Milkdrop Visualizer, the album image remains, the text to click through to the next image is gone, while the new milkdrop visualizer related text appears in the top right of the image view, but no visualization is visible (says "Default", then below FPS: 0).The recommended preset pack was downloaded upon promted beforehand.

When running Tauon through the terminal, it says "Could not find libprojectM-4 (t_main.py:36307)", but in apt i only see libprojectm2v5 available to install. Installing that didnt help either.

To Reproduce

Steps to reproduce the behavior:

1. Go to Menu, go to the view mode at the very top
2. in the Album image pane on the right side, click on 'Enable Milkdrop Visualizer.'

Expected behavior
Animated visualisation to appear

2026-02-26 18:43:41 [WARNING] [ t_main ] Could not find libprojectM-4 (t_main.py:36307)

[C0rn3j]

in apt i only see libprojectm2v5 available to install. Installing that didnt help either.

Debian (-> Ubuntu -> Mint) carries an extremely outdated version of libprojectm so that wouldn't work even if this weren't a Flatpak - and since it is a Flatpak, it does not use system dependencies, it should Just Work™ as we ship libprojectm from within it.

Can you run these?

flatpak run --command=bash --devel com.github.taiko2k.tauonmb

find / | grep -i libprojectm

It should return

/app/lib/libprojectM-4.so.4.1.0
/app/lib/libprojectM-4.so
/app/lib/libprojectM-4.so.4

[Grassgrowz]

Hey thank you for the quick response! yes im seeing all three of them, running the above commands returned:

/run/host/usr/share/doc/libprojectm2v5
/run/host/usr/share/doc/libprojectm2v5/README.Debian

/app/lib/libprojectM-4.so.4.1.0
/app/lib/libprojectM-4.so.4
/app/lib/libprojectM-4.so

[C0rn3j]

Hm, how about this?

flatpak run --command=bash --devel com.github.taiko2k.tauonmb

python -c "import ctypes.util; lib_name = ctypes.util.find_library(\"projectM-4\"); lib = ctypes.CDLL(lib_name)"

I actually get a OSError: /app/lib/libprojectM-4.so.4: undefined symbol: eglGetProcAddress error there, which is fairly bit odd, since the app works fine during normal usage, I wonder if the devel env is somehow different.

EDIT: This may be more telling

flatpak run --command=bash --devel com.github.taiko2k.tauonmb

python -c "import ctypes.util;  ctypes.CDLL(\"libEGL.so.1\", mode=ctypes.RTLD_GLOBAL); lib_name = ctypes.util.find_library(\"projectM-4\"); lib = ctypes.CDLL(lib_name)"

[Taiko2k]

So /run/host/usr/lib/libprojectM.so.2 is listed there, if that is getting loaded that would cause that issue. Not sure why that is being preferred over the bundled version.

[Grassgrowz]

Running the first mentioned command returned this:

misha@disnuts:~$ python -c "import ctypes.util; lib_name = ctypes.util.find_library(\"projectM-4\"); lib = ctypes.CDLL(lib_name)"
Traceback (most recent call last):

    import ctypes.util; lib_name = ctypes.util.find_library("projectM-4"); lib = ctypes.CDLL(lib_name)
                                                                                 ~~~~~~~~~~~^^^^^^^^^^

    return _dlopen(name, mode)
OSError: /app/lib/libprojectM-4.so.4: undefined symbol: eglGetProcAddress

Running the second command returned nothing at all.

[C0rn3j]

Okay, a different approach then. This is presuming you do NOT currently get a message in the GUI about it but only in the log, as otherwise it's failing way too early for any of the following changes to help.

If you DO get the message ("Package ProjectM-4 not found", "Milkdrop feature will be unavailable",) in the GUI, let us know and ignore the content below.

---

Backup your current user data directory just in case - /home/misha/.var/app/com.github.taiko2k.tauonmb/data/TauonMusicBox

Download the .flatpak file from https://github.com/C0rn3j/Tauon/actions/runs/22482769179?pr=2046 (it will be there in about half an hour from the time of posting)

# Delete Tauon
flatpak remove com.github.taiko2k.tauonmb

# Install the custom version
flatpak install tauonmb.flatpak

Then get the error again and post the log again, then we'll at least know on which line it's failing and can go from there.

[Grassgrowz]

I saw no messages regarding the ("Package ProjectM-4 not found", "Milkdrop feature will be unavailable",) in the GUI ever, so i will be trying the further steps you provided.

Ok I backed up my user data, deleted my current install and installed the flatpak from your provided link, heres the terminal output of starting Tauon and attempting to start the Milkdrop Visualizer:

Please show output of

flatpak run --command=bash --devel com.github.taiko2k.tauonmb

find / | grep -i libEGL

What GPU/driver do you have?

[Grassgrowz]

Im currently away and wont be back at my PC until Sunday, which is a Lenovo Legion 5 with a mobile nvidia RTX 3060 with the 580 driver version.

Im at my girlfriends place and she actually has the very same bug/error occurring, also installed per flatpak. She is running Mint 22.3 with the 6.17.0-14-generic kernel, AMD Ryzen 9 5900X and GeForce RTX 3060 Lite Hash Rate with the 590.48.01 driver. I ran the previous commands and had the very same output.

I uninstalled and installed the most recent version you provided earlier.

The output to "find / | grep -i libEGL" is;
