    your thermocouple is loose and moving a little during printing, changing the temp values and then the temp is being shot back up to compensate, meaning more heat and different characteristics for your ABS ?

    just an idea...

    Are those bulges at the same height on the two objects? They appear to be, which to me would seem that your z axis ball screw might be slightly out of adjustment??? Maybe check the platform screws around the bearings and loosen/re-tighten your ball screw coupler? The other thing to consider would be adjusting your flow rate. Since you are saying those are on solid layers I would think your flow rate is slightly too high.
