Shader compilation hickups during runtime


When i run my quite simple scene with a few point lights when i fly around the scene there are quite long hickups (about 10-30 sec) and memory goes from 300mb to 1-2gb.
it seems to compile shaders since i get lots of implicit conversion errors in the console.
Is that a know issue? can it be something i did?


The long hickup was from the debugger. but its still a quite noticeable hickup in the release build
