Hi Felix, I'm sorry I just don't have any idea how Pipe would affect other apps that way. You mean it affects other apps even after the Pipe command is finished? Or only while it is running?

Maybe there is some problem with your video driver and it is manifesting itself in strange ways like that. That's about the only thing I can think of, maybe try to update your video driver to the latest version and see if things improve any...

And yes, the original Pipe command did need an update in order to run on v3, the version you need is the one from here:
