Focus hunting with Canon EF 70-300mm f/4-5.6 IS USM when adapted to EOS RP

I just got the EOS RP with the EF adapter. While most EF lenses seem to work fine with the adapter, but I ran into focusing issues with the Canon EF 70-300mm f/4-5.6 IS USM (https://www.dpreview.com/products/canon/lenses/canon_70-300_4-5p6_is)

It seems that with AI servo mode the focusing never stops even though the subject and the camera are not moving at all. I have used this lens with my previous camera (550D) extensively and never had such issues.

Has anyone else the same combination? Same problems?
