Description
See investigation in QDS-6885. According to that, it seems that significant portion of puppet load time after puppet reset is spent generating/compiling shaders. This is also done for three different puppets at the same time, which worsens the problem.
Investigate if there is some viable options to cache shaders to speed up scene loading.
A separate implementation task can be created is a viable way to improve the situation is identified, or the implementation can be done in context of this task.
