ok this happen when i go to view the lighting options in the editor, normal i just use “Lit” and “wireframe” but when checking for a problem for some one else i moved the mouse further down the list, just holding the mouse over the “Visualize Buffer” section of the menu causes Rocket to crash with the following report
here the crash paste
