Hello. I just downloaded and installed Houdini from official site (I have Arch Linux x64 and KDE on it), but when I did “source houdini_setup” and “houdinifx” I saw this window: How to see the text?
That looks like a graphics issue to me, that or that you're running into the $HOME/houdini14.0 file permission issue. To rule out the latter, you can running “sudo mv $HOME/houdini14.0 $HOME/houdini14.0.orig”
