High CPU usage on powerful laptop running Ubuntu 16.04.4 LTS

I have a relatively powerful laptop:
-Computer-
Processor : 8x Intel(R) Core(TM) i7-6820HQ CPU @ 2.70GHz
Memory : 32859MB (2612MB used)
Operating System : Ubuntu 16.04.4 LTS
-Display-
Resolution : 3840x1600 pixels
OpenGL Renderer : Quadro M2000M/PCIe/SSE2
X11 Vendor : The X.Org Foundation
-Multimedia-
Audio Adapter : HDA-Intel - HDA Intel PCH
Audio Adapter : HDA-Intel - HDA NVidia
I have to use Ubuntu 16 LTS on it.
My issue is that when I open a window and just move it around slightly the CPU usage by xorg jumps to almost 100%.
At first I thought that the build-in graphic card was being used and that was making the CPU work harder, but the output from the following shows that the NVIDIA card is indeed being used.
~$ glxinfo | grep render
direct rendering: Yes
OpenGL renderer string: Quadro M2000M/PCIe/SSE2
GL_ARB_conditional_render_inverted, GL_ARB_conservative_depth,
GL_KHR_robustness, GL_KTX_buffer_region, GL_NVX_conditional_render,
GL_NV_conditional_render, GL_NV_copy_depth_to_color, GL_NV_copy_image,
GL_NV_path_rendering, GL_NV_pixel_data_range, GL_NV_point_sprite,
GL_ARB_compute_variable_group_size, GL_ARB_conditional_render_inverted,
GL_KHR_robustness, GL_KTX_buffer_region, GL_NVX_conditional_render,
GL_NV_conditional_render, GL_NV_copy_depth_to_color, GL_NV_copy_image,
GL_NV_path_rendering, GL_NV_pixel_data_range, GL_NV_point_sprite,
GL_EXT_protected_textures, GL_EXT_render_snorm, GL_EXT_robustness,
I am using the proprietary Nvidia Driver 384.111, which is relativly new.
Any ideas why my CPU is so jumpy when moving a window (or even tabbing between different windows)?

On my own system the Gtx 970M makes system 20 C hotter and windows lag moving them.

Do things improve afterprime-select intel(switch to iGPU) followed byreboot?
