Bug Weird texture / shader graph issues.

Hello everybody, I was forced to update to 2019.3 due to a weird console bug (blank error codes) that I could not resolve in 2019.27f. Anyways there is no way to backtrack my project as it's permanently been moved to 2019.3 without resetting up all the project files. Everything seems to be in pretty good shape (possibly better than before), except a few texture, shader graph issues.

I've uploaded example problems I've been having, hopefully these are relatively simple issues that somebody can help resolve. Thanks in advance!

I'm not using any special post processing, and these issues persist with them being turned off. The shader graphs for them are relatively simple as well, they do not use any kind of special depth buffering or zwrite techniques. They are either simple flow maps with/or intense colors + noise masks on the unlit shader graph.
