Hi, I have the same two lenses (10-22 and 24-105), both with permanently attached Hoya Pro1 UV-filters that are rather slim. My 77 mm CPL is a basic Hoya HMC polarizer that you wouldn’t call slim, and when they are stacked (Hoya Pro1 + Hoya HMC CPL) on the 10-22 there’s mechanical vignetting up to around 12 mm focal length. However - as already mentioned - the CPL effect at really wide angels is tricky since the CPL effect highly depends on the shooting angle (vs. the sun). By experience I avoid focal lengths below around 16-17 mm when using the CPL, so for me the mechanical vignetting at 10-12 mm isn’t really an issue.
