Texture DXT quality drop from Unity 2018.3 to 2019.1

I just updated to Unity 2019.1 from 2018.3, and noticed something is wrong with the textures DXT compression.



In 2019.1 there is clear compression artifacts with the color gradient (check the floor and the face). While in 2018.3 the gradient are smooth.



In the change-log it is mentioned: Asset Import: Improved performance of DXT1/BC1 and DXT5/BC3 Texture compression This does not affect compression quality, but it does probably produce subtly different compression results.

Am I missing something? What can i do About this? It essentially makes DXT compression useless, and I suppose my only option is to crunch all the textures or go back to 2018.3.
