phpstorm hangs sometimes when maximizing the IDE again

Hi,

since I have reset my folder exclusion to the recommended settings from the Shopware project (less exclusion), my IDE hangs sometimes (most of the times) when I maximize the window again. Due to the timestamps in idea.log I found a repeated error which equals the maximize timestamp:

Before, I have excluded the /var folder completely. Now, only /var/log is excluded as recommended from the project: https://developers.shopware.com/developers-guide/phpstorm/#configure-project-directories

The Shopware version I am using equals to the latest tagged 5.2 Git Version, which can be found here: https://github.com/shopware/shopware

Usually when this hang happens, I have running my Grunt watcher and an opened database connection to the MySQL Shopware database scheme.

I tried to increase the XmX JVM Memory exponentially, but this didn't help.

Any help to this topic would be great, since I am not sure if this is a bug or not. Maybe it only appears on huge projects like Shopware. I am using MacOS Sierra Version 10.12.5.

Thanks,

Thomas
