Texas population growth was not suppressed to nearly the degree of Arkansas. Texas numbers were 213,000 in 1850; 604,000 in 1860; 819,000 in 1870; and 1,592,000 in 1880. The period of 1860 to 1870 produced three times as much population growth in Texas, 35.5% as in Arkansas, 11.3%. Of the former Confederate states, only Florida had similar growth as Texas during that period.
It is possible that individual counties in Texas suffered considerably, but I have not taken a look at that. (Earlier I did look for that county effect in Missouri and didn't notice population loss where I thought I would, Missouri had higher growth than Texas from 1,182,000 to 1,722,000 in the same ten year span.)
It was the sustained stunting of growth in Arkansas in the 5 years after the war that really drove home the problem to me.
