contents We prove that minimizers of variational integrals $$ \mathcal E(v)=\int_Ωf(v)\quad\text{for }v\in\mathcal M(Ω)\text{ such that } \mathscr{A} v=0, $$ are partially continuous provided that the integrands $f$ are strongly $\mathscr{A}$-quasiconvex in a suitable sense. We consider linear growth problems, linear PDE operators $\mathscr{A}$ of constant rank, and variations of the form $v+φ$ with $\mathscr{A}$-free $φ\in \mathrm{C}_{\mathrm{c}}^\infty(Ω)$. Our analysis also covers the ``potentials case'' $$ \mathcal F(u)=\int_Ωf( \mathscr{B} u)\quad\text{for } u\in\mathscr D'(Ω)\text{ such that }\mathscr B u\in \mathcal M(Ω), $$ where $\mathscr{B}$ is a different linear pde operator of constant rank. Both our main results extend to $x$-dependent integrands.
