High CPU usage issue

[alexbet]

Actual Behavior

Many times CPU goes to 100% when saving an SCSS file for some reason and locks SublimeText for 5-10 seconds. At the time that his happens, I can see that a process called "plugin_host" which is a Sublime process use up 100% of the CPU. If I disable the Javascript Enhancements plugin, everything is normal. Very weird because the SCSS file has nothing to do with Javascript.

I can't get this scenario! On my Mac I don't have this problem.
Do you have some other plugins for scss files?

[alexbet]

The only ones I use are these:
https://packagecontrol.io/packages/Sass
https://packagecontrol.io/browse/authors/Kenneth%20Skovhus

Just FYI, this doesn't happen all the time, but sometimes only, but I can't predict when it will happen. It may also be helpful to know that my files are on a mounted network drive. It is weird that this doesn't happen on Javascript files or any other files. I am really confused why your plugin will have anything to do with SCSS files.

I love your plugin! I just hope I can somehow solve this so I can use it.

[pichillilorenzo]

Ok ok.. This is weird because I don't consider scss files on my plugin, so it has no sense to happen. I will try to check about it! Thanks

[alexbet]

Could it be some conflict with the the SCSS plugin?

[pichillilorenzo]

I don't know but it could be

I can reproduce this with normal CSS files.

Here's my related console error logs:

@trongthanh I think that this is a bug of a function of Sublime Text API: view.substr().
In case, can you post here or send me the css file that causes that?
@alexbet also you, can you post here or send me the scss file that causes that??
Thanks!

[alexbet]

Hey @pichillilorenzo , here is a file that does this. However, basically any SCSS file does it.

main.scss.zip

[alexbet]

@pichillilorenzo, any news on this? I still can't use your plugin because of this and I really want to use it. Is there any way that you can disable scanning of Scss and Sass files?
