Compactness of the minimal elements of quasicomplemented posets

From papers

Let QQ be a poset, and write Min(Q)Min(Q) for its set of minimal elements. Suppose that QQ is quasicomplemented and belongs to the class PMFP\mathbb{P}^{\ell}_{MFP}, and that it satisfies the condition a.c.a.c.

Compactness conjecture. Is Min(Q)Min(Q) compact?

The question is motivated by the preceding example of a quasicomplemented poset in PMFP\mathbb{P}^{\ell}_{MFP} without a.c.a.c. for which Min(Q)Min(Q) is not compact; the conjecture asks whether the additional a.c.a.c. hypothesis guarantees compactness.
