Script compilation broken again in 5.3.4p3, any was to fix it?

I upgraded from 5.3.2p2 to 5.3.4p3 and once again, regardless of whether scripts are in Standard Assets or not, all scripts are compiled every time when any script is saved. This can lead to very lengthy compile times if you have a lot of large scripts, especially if they're "Javascript" scripts.

This was also a problem in the versions directly preceding 5.3.2p1, then it was fixed, and now it's happening again. If there any way to fix this without having to downgrade?

 

Have you tried deleting your temp and library files?

 

A three hour full re-import later and... no it's not fixed.

It's definitely a problem with 5.4.3p3 cause I can immediately switch back to 5.3.2p1 without a re-import or anything, and compile times are normal.
