Totally agree we need to fix these issues with lines and ID requirements. But Texas and California are very different.
California has mail-in so I do think something is going on where people don't know about the vote by mail. You can even just get your ballot by mail and drop it off at a polling place or mailbox day of if you want to decide late.
And gerrymandering is definitely a huge issue, but not the whole issue. You can't gerrymander the Senate, for example, but it is still Republican-controlled.
It does seem like there are still extreme get-out-the-vote issues beyond the (totally unacceptable) vote suppression. Turnout is still unbelievably low.
They close voting sites in these places, sometimes the day of the election:

They come up with convoluted ID requirements that only apply to college students, requiring types of ID their colleges don't even issue for them:

That doesn't happen in rich white neighborhoods. It's nothing if not voter suppression.
That's not even to bring up gerrymandering. I mean look at these voting districts that have been drawn:
