[SOLVED] Wayland - Some inputs don't work in multiple u-he plugins

[virusav]

I recently switched to Wayland full-time after switching from Nvidia to AMD on a new build PC. Everything has been surprisingly solid, apart from one thing... Now, a bunch of inputs in u-he plugins don't work, in Bitwig (5.2.4).

Is this a known issue, and is it something that is likely to get resolved at some point in the non-too-distant future, by any chance?

Examples:

Repro 5
- Voices
- search presets

Diva
- search presets

Hive
- Voice mode
- Voices
- search presets
- numerous other

Bazille
- search presets

Thanks in advance

Hi, this is not a known issue, thanks for mentioning.
But I cannot say if our plugins are compatible to Wayland, this is nothing we ever tested so far.

[virusav]

Thanks tasmaniandevil for letting me know.

Hopefully Wayland testing will come into play at some point for u-he plugins. Quite a few modern distros are switching away from Xorg and adopting Wayland instead.

I've tried switching several times over the years from Xorg to Wayland, but it never felt quite ready and I had various issues that meant I switched back to Xorg. Since making the switch about 3 months ago, everything has been great and I can't see myself every going back. This u-he interface bug doesn't warrant switching back to either, but it does mean I can't use all my plugins to their full extent, at least not yet.

My fingers are crossed that this comes onto the devs radar sooner rather than later.

Thanks to all at u-he for the super awesome plugins, and MAHOOSIVE thanks for the Linux support to boot.

Do you have XWayland installed on your computer? It is a 1:1 installation of Xorg, under the control of Wayland. Xorg compatibility is 100% supported by Linux, through Wayland with XWayland. What distro are you using? Check and confirm that you have XWayland installed. If you do, then the problem is not with Wayland.

I recently updated to latest Kubuntu, which switched to using Wayland as default, and I'm not seeing these issues on my end. Search and various dropdown menus in Hive and Diva seem to work fine. (REAPER + clap versions.)

Yeah, I have it installed. I just checked if Bitwig is using it and according `xlsclients -l` it is not.

I tried forcing Bitwig to use it with `env -u WAYLAND_DISPLAY bitwig-studio` and that didn't work either.

I'm running Arch (btw).

It's really weird, when I click UI components in the synth that don't work, then I can visibly see the "undo" button in the Bitwig interface click.

You're on KDE and I'm on Gnome, which could very well play a part in why you're not seeing the issue.

Just checked the `engine.log` for Bitwig and I'm seeing the "MouseUp Without Tracking" event every time I click one of the UI elements that isn't working:

Also, not sure where the "jenkins" user is coming from, unless it's some build pipeline used for the plugin, as that is not my username

I've installed bitwig-studio via the AUR (as opposed to using the flatpak version, which I've had issues with in the past for things like VSTs).

It's also worth mentioning that when I launch Bitwig via the following command, then it shows a splash screen, which is not something that happens when launched without the prefix.

Code: Select all

GDK_BACKEND=x11 bitwig-studio

Even when launched with the prefix, the app is not listed in `xlsclients`.

Noticed that java apps might not always play nicely with Wayland
(https://discourse.ubuntu.com/t/environm ... kers/12750)

$_JAVA_AWT_WM_NONREPARENTING

Many Java apps (such as Intellij) don’t support Wayland natively and break on most XWayland implementations (and other non-reparenting window managers). This often results in blank screens. To make them work, set _JAVA_AWT_WM_NONREPARENTING=1. I consider this a toolkit bug, but it seems unlikely to be fixed.

Had a play around with various launch prefixes, e.g.

Code: Select all

_JAVA_AWT_WM_NONREPARENTING=1 XDG_SESSION_TYPE=x11 WAYLAND_DEBUG=1 GDK_BACKEND=x11 bitwig-studio 
[2024-11-4 22:48:1.294 info] About to start the following process:  /opt/bitwig-studio/bin/show-splash-gtk /opt/bitwig-studio/resources/splash-bitwig-studio.png

Then noticed the process that is launched:

Wondered if that was somehow not adhering to Xwayland.

I recently updated to latest Kubuntu, which switched to using Wayland as default, and I'm not seeing these issues on my end.

Are you using the deb package, or the flatpak? What does the launch process look like if you start it via a terminal? e.g.

Code: Select all

/opt/bitwig-studio/bin/BitwigStudio -cp /opt/bitwig-studio/bin/bitwig.jar:/opt/bitwig-studio/lib/cp:/opt/bitwig-studio/bin/libs.jar -Dorg.sqlite.lib.path=/opt/bitwig-studio/lib/bitwig-studio -XX:+UseZGC -XX:+ZGenerational -Xms300m -Xmx3g -Djava.io.tmpdir=/tmp/bitwig-keito -DinstallationRoot=/opt/bitwig-studio -DsplashPid=78400 -Djava.awt.headless=true -XX:ErrorFile=/home/keito/.BitwigStudio/bitwig-studio-jvm-crash.log com.bitwig.flt.app.BitwigStudioMain

EDIT: Ignore me, just re-read and you're using Reaper.

Also, are you using a HiDPI screen with any scaling?

I'm on 1080p, no scaling, for what it's worth.

And yeah, I'm on KDE—that could of course be a factor. Though Gnome has been using Wayland as default for longer than KDE has, so I feel like if many people were having issues with it, we would have had more reports?

And I was recently playing around with the trial version of Bitwig as well, and noticed no obvious problems. BUT I can't remember for certain if I accessed any of the specific features you were having issues with. Unfortunately I no longer have Bitwig installed, so I can't test it now.

[virusav]

FWIW I chatted to Bitwig regarding the captured logs to see if this is an issue they need to fix their end, but they responded saying that the problem exists within the u-he plugin. Hopefully, as more users transition to wayland, this will become an issue that warrants some attention from the devs.
