Curious Richard, you mention that Nvidia graphics are more mature than AMD, in what way? 

Another screenshot...

For the CPU load, temps are well within spec and since the CPU isn't used hard... cpu temps are low.. CPU temps are relative to what cooler you have on the CPU and the cooling of the overall case. I am using a Phanteks P400a, stock AMD cooler, even though I have an Arctic Freezer 240 sitting the box. The stock cooler has never had an problem ...

Also, have you ...

That was my first thought.... a 14'' laptop....

The reason that you lost the name of the project in the 3rd image (in your post), is because you were in Pan and Zoom view, and not the Timeline view where the project name will be. Click on it and the disc name will appear.  The reason I asked what ...
