Hello,

I have this problem since a few days now on Houdini 17.5.460

When a drop any vex related node (point vop, wrangle, mountain …), Houdini freeze for 1-2sec when I drop the node and it freezes again for 1-2 sec each time I try to change a parameter and it says bottom left “duplicating inputs” and “executing vex”.
It only happens when the viewport is visible, so there is some problem with vex and viewport.
I have a GTX 1060 with updated drivers from nVidia (445.87).

Does someone have an idea what could be the problem?
Thanks

Try clean your houdini_temp folder.

on windows you can find it here:
C:\Users\<user>\AppData\Local\Temp\houdini_temp
