RE: Does anyone else have this problem?
Are they both the same size pins (.029" vs. .019")? The finer pins would help you focus better, so would better lighting or a larger peep. I get the same halo effect on my pins as the light fades. It doesn't much bother me in closer because the target looks larger but out farther (40+ yards) it makes it very hard to discern. You could try shooting at a larger target too (single spot vs. 5 spot) so that the halo still centers in it rather than blotting it out.
