No updates... There is absolutely no Wayland support in Houdini. Possibly 21.5 or 22.0? This is just a guess.

It's quite frustrating, I upgraded to ubuntu 25 so I have this issue too.

You can fix the scrolling issue (or at least it did for me) by installing the qt5 version of houdini. Sadly, houdini isn't very stable though on wayland.

Edit: I didn't see the posts before, looks like you already tried this.

Yeah.. it is how I am working now... using Qt5. There is another issue that I think might be related to all this. Even with Qt5, if I middle mouse click and hold on a parameter (1.0) for example, sliding left and right, it will skip to a huge number.

I have this problem on Ubuntu 26.04/Gnome 50/Wayland as well.

Holding space works for the graph editor (although hardly great), it also affects scrolling in file browser or parameter windows. If I hover over the scroll bar on the parameter window it does seem to work and so does dragging a value around on a parameter with the middle mouse button.

Hoping to avoid going back to Cinnamon, but this is pretty obnoxious.
