Hi, when I wanted to check something lately in tutorials I found something strange. Some of tutorials looks as below:

It's only happens in few tutorials (mostly from Rendering folder).

I have laptop with two GPU, Intel HD Graphics 4000 and AMD Radeon 7670M. When I manualy set built app to use Radeon, everythink back to normals, but when my laptop try to automatic set graphic card choose Intel, and issue appears.

I don't have this problem with my project, so it's not really important to me, but maybe this is some kind of bug.
