I know you aren't claiming that's true, but for anyone who thinks it is true, and since you asked for evidence, here are some bits of it.
Demographic change in California isn't really different than other similar states. California's racial and ethnic demographics are [1] pretty similar to Texas [2]. Most of the west and southwest is getting less white, with few exceptions.
Both states' populations (and population growth) are primarily concentrated in their cities, with rural areas continually emptying.
The only difference is overall population growth rate, which has declined in CA, due mostly to economics, and specifically the very high housing costs, which tend to inhibit immigration by lower and middle income workers more than higher income workers.
