Slimes can be clearly seen through nether portal blocks.
If a slime is on the other side of a little portal, it can still be seen even with the portal blocks there, I used a sheep in the example to compare a normal mob and a slime. This isn't really a problem it just bothers me. See the screenshot below for the comparison.
