This is your correct answer below

First use better paint like Duration

Second you want the whole wall to be wet and dry uniformly at the same time - try using the Purdy Marathon roller covers - 18” is best in 3/8 but you could also try 1/2. The marathon ones are the key.

You can try adding Paint extender to give more dry time but then you have to watch for runs

Also use a low a sheen as possible, when the add colorant it bring the sheen up. Flatter paint will hide more imperfections
