Code Highlight/Completion/Inspection Doesn't Work on certain files

[richerarc]

Hi, I don't know if this issue belongs here, but I've never experienced this issue with an other language.

I'm using intellij-rust v0.2.95.2120-191 with CLion 2019.1 on macOs 10.14.3.
It's an issue that seems to persist across the la 3-4 plugin version and upgrading / downgrading CLion doens't change anything.

Here's the issue: In some .rs files (anything larger that 600 lines) the code highlights stop working as well as the code inspection and the code completion. Strangely enough, some file with more than 800 lines on code render well with color and everything but other files less than 300 lines will stop being inspected or highlighted at some point. here are some screenshot illustrating the issue: screenshots

At this point I tried disabling every single checkbox from this plugin hoping it would somehow behave differently but it did do much.
