  We investigate full QCD with (2+1)-flavour of HISQ fermions at the physical
point in the presence of uniform Abelian chromomagnetic background fields. Our
focus is on the renormalized light and strange chiral condensate around the
pseudo-critical temperature. We find that in the confined region the gauge
system is subjected to the chromomagnetic catalysis that turns into the inverse
catalysis in the high-temperature regime. We further observe that the chiral
condensates are subjected to the so-called thermal hysteresis. Our estimate of
the deconfinement temperature indicates that the critical temperature begins to
decrease
  in the small field region, soon after it seems to saturate and finally
increase with the strength of the chromomagnetic field.
