CPU high in SCORM-course on pages with smart shapes makes keyboard shortcuts stop working

Using Captivate 9

We experience issues in the published content when installed in an LMS.

Target LMS is Moodle-based but the issue appears on other LMS-systems as well.

Specificly on pages that contain smart shapes the CPU runs very high (constantly on 80% even on a powerfull machine).

The issue onl appears in LMS not in a web-link and not on pages without smart shapes.

This causes pages with keybord shortcuts to stop working in some places.

Thankful for any input!
