No, you only pay for time worked in CA. The only exception I found are options/RSUs granted in CA and vested after you've left, these may be taxed in proportion to the time originally worked in CA after the grant.

RSUs are taxed in state where granted

Non-Quals are prorated

ISOs are taxed in state where exercised

For CA, ISOs and RSUs are prorated if holding requirements are not met. https://www.ftb.ca.gov/forms/misc/1004.html, it has a summary at the bottom
