Linux Crashes (4.6/4.7)

It seems that if I open UE4Editor, the Project Creation comes up fine… But if I take too long, it hangs… Similarly, if I create a Project and click on a tab inside the editor… It crashes… It seems like Linux version is so buggy… It feels like I’m paying for a product that’s so fragile doing anything with it will break it… How am I to make a Game with these conditions? My environment is Linux, and I refuse to go to Windows… It’s the reason I chose UE4 over Unity. Any help would be excellent (if you need Debug logs, let me what to do for you)

What are your distro, hardware, and drivers? And yes, please attach the logs.

Sorry for the delay! Been busy…

Distro: Ubuntu 14.10 64bit.
NVidia: GeForce GTX 660M
RAM: 8GB
Processor: Intel i7 (3rd Gen) 2.30ghz

Open a Project, click the Second Icon on the Left (looks like a PaintBrush) and it crashes, everytime.

Hmmm… Clicking on anything with updated 4.7 (GIT) causes that crash, any UI Element it seems?

Any word on fixes for this?

This shouldn’t happen with current 4.7.
