Mouse Scrolling Issue 2026年2月22日20:49
Can confirm this is still a friggin' issue and it's very frustrating. I have multiple Linux bugs that make the whole Houdini situation the one snag in my Linux life (I've been in the process of switching the past month).
Currently running an Arch distro called CachyOS using KDE Plasma 6.6. I love it. Plasma is great. Cachy is great. Nuke works flawlessly. Games work flawlessly.
Houdini...it's the little things. The damn middle mouse button. Installing the QT5 version DOES fix it, however, V-Ray doesn't work in the QT5 version!
Furthermore, I have to downgrade to the 580 Nvidia drivers otherwise Houdini will randomly freeze up every few seconds to every few minutes. This isn't the end of the world, but I do experience some minor crashing in games I don't otherwise have.
Hell, I even got Anyware client working with Distrobox for the day job at the studio. It's literally these couple of small issues that can be quite a headache that are keeping me from completely formatting my Windows drive.
Anyone else have these issues or any workarounds?
Oh and by the way, I have tried myriad other distros and DE's at this point. The only DE I've found that doesn't seem to be problematic is Cinnamon. But also...gross.

Python Error In Linux But Not Windows 2026年2月9日20:43
I wondered about that too, but what's weird is I'm not using V-Ray in this particular script. I was just trying to import an Alembic camera into Karma/Solaris. I'll post on the Chaos forums too though. Thank you for the response!
Python Error In Linux But Not Windows 2026年2月9日13:56
Hey all
I think I may have found a bug but I'm new to Linux so wanted to make sure I wasn't crazy before reporting it. I have a scene that works fine in Windows. Everything is good. In fact, it also works fine in Linux.
I'm loading in an Alembic camera into the obj context and everything works great. I'm then importing that camera into a LOP context withe a sceneimportcameras node. Again, on Windows, everything works great.
However, when I go into the LOP context, that same sceneimportcameras node throws a python error and suddenly the camera won't work. This is the error:
Then, another one comes up:
This just repeats in perpetuity.
I have package files I've setup to redirect my file paths between Windows and Linux, so I thought that maybe that was it. However, when replacing the Alembic with native Linux file paths, I still get the issue.
It's worth that that the Alembic loads and works fine in the object context, but as soon as I switch to LOPs that's when I start getting issues.
I'm running an Arch distro called CachyOS. So far, everything has been fine except for the incredibly obnoxious middle mouse issue everyone else seems to be having.
