I did a fresh Ubuntu install this is the video and the bug list.. http://tinyurl.com/onbdpls -Pretty laggy windows. -The viewports works great, when you rotate with alt+ right button is pretty smooth, but using alt + left button is not that perfect, I try it on blender and it responds great using both buttons. - F2 doenst work to rename, and F11 to maximize it takes around 1 second, on blender it does it instant. -If you add a component to a object with the same component appears a window with a button without text. -I export a project and exports perfect and runs perfect, but the button for save the file says "open" instead of save. -Drag and drop doesn't work.
