Metroid Other M Stuttering

[DolphinPC]

I know and sure it's because of the shader generation, but sometimes there's a 2 seconds long stutter. tried both OpenGL and Direct3D, I even disabled idle skipping and dual core but nothing helped. it happened on both windows 7 and 10. I tried the latest development builds from the last 2 months. I never saw anyone who complained about this, so is this common with this game? is there anything I can do besides play and build the shadercache?
