Houdini 22 no longer provides a Qt 5 build, but I’ve been able to use it on Wayland without issues by adding the following lines to houdini.env:

QT_QPA_PLATFORM=xcb
QT_XCB_NO_XI2=1

Thanks a lot! I knew about the second line but not the first one. What exactly do these do? The first line actually fixed the issues I had on my miniPC

@racoonart From what I've read the first one makes you use X11 backend resulting in XWayland instead of Wayland. The second one disables XInput2, some exetension related to input handling.

That makes sense

Thanks! I assumed XWayland was used automatically, but apparently that's not the case. That would explain a few things.
