I’m seeing the same issue on a client site using the Roseta theme. We tested with both third-party plugin shortcodes (Pods Framework) and a generic shortcode, and neither rendered — confirming this isn’t plugin-specific. The recursion protection introduced in 1.4.0 has removed shortcode processing from slide content entirely.
The issue appeared with 1.4.0 and 1.4.1 has not resolved it. Rolling back to the previous version restores the expected behaviour.
lazyleopard’s suggestion is exactly right — the fix should block only the slider’s own shortcodes from being processed recursively, not remove do_shortcode() from slide content output entirely. A simple exclusion of the slider’s own shortcode tag would solve the recursion problem without breaking everyone else’s use case.
Is there a filter we can use in the meantime to restore shortcode processing in slide content?
